Top 10 Indian Serial Killer Movies to Watch If You Like Ratsasan

Let’s be honest: finding a truly gripping crime thriller is exhausting these days. Most movies reuse the same old stories—villains killing for money, family drama, or basic revenge. But if you are a hardcore thriller fan, you probably want something much darker. You want to see the twisted mind of a pure psychopath playing a dangerous mind game with the police. Ever since movies like Ratsasan came out and completely blew everyone away, the standard for Indian suspense cinema has gone through the roof.

The good news is that Indian filmmakers are no longer holding back. From Bollywood to the South, we are getting brilliant, dark, and intense stories that can easily compete with international thrillers. If you love stories that keep you guessing until the very last minute, you are going to love this list. From high-tech forensic investigations to chilling real-life inspired cases, here are 10 incredible Indian serial killer movies you should add to your streaming watchlist right now.

10. The Stoneman Murders – IMDb: 7.3

• Where to Watch: Prime Video, MX Player (Free), Jiohotstar,
• The Cast: Kay Kay Menon, Arbaaz Khan, Vikram Gokhale, Virendra Saxena
• The Killer’s Pattern: Targetting people sleeping on the streets and crushing their skulls with a heavy stone in the dead of night.

Did you know that back in the 1980s, the pavement dwellers of Mumbai were terrified of falling asleep? This film brings that real-life, unsolved mystery to the screen. The story drops us right into the damp, dark alleyways of old Bombay, where a suspended police officer decides to track down this faceless killer on his own, hoping to get his badge back.

The Stoneman Murders doesn’t rely on flashy cinematography or heroic entry scenes. Instead, it focuses on the gritty, raw reality of a police investigation during an era when DNA testing and mobile phones didn’t exist. It’s a dark, slow-burn mystery where the atmosphere itself feels like a character.

In my opinion Kay Kay Menon is a powerhouse, and this film proves why he is one of the best actors we have. If you are tired of modern thrillers that rely too much on technology and gadgets, this grounded, old-school detective story will feel like a breath of fresh air.

9. Mardaani 2 – IMDb: 7.3

• Where to Watch: Netflix, YouTube (Rent)
• Cast: Rani Mukerji, Vishal Jethwa, Virti Vaghani
• The Killer’s Pattern: Stalking independent young women, brutally torturing them, and leaving them for dead while openly mocking the police.

Most crime thrillers hide the villain’s face until the very end, but this film takes a completely different route. It introduces you to the killer in the first few minutes, and honestly, that makes it even scarier. We see a young, terrifyingly polite boy who changes his look, accent, and behavior in seconds to blend into any crowd.

Rani Mukerji returns as a fierce, no-nonsense cop but Vishal Jethwa steals the entire show. His performance is so intensely creepy that you will find yourself genuinely angry at the screen, just waiting for him to get caught. If you want a fast-paced thriller that doesn’t waste any time, this face-off is a must-watch.

8. HIT: The Second Case – IMDb: 7.2

• Where to Watch: Prime Video
• Cast: Adivi Sesh, Meenakshi Chaudhary, Komalee Prasad
• The Killer’s Pattern: Murdering young women and surgically stitching different body parts together to display them like a puzzle.

This installment pushes the ‘HIT Universe‘ into a much darker territory than the first one. Adivi Sesh plays the cool-headed cop effortlessly, and the surgical precision of the mystery keeps you guessing. If you love tracking clues alongside the detective, you will have a great time with this.

The main character is a laid-back, overly confident officer who gets a massive reality check when a local gruesome murder turns out to be the work of a highly methodical psychopath. The crime scenes are intense, and the investigation dives deep into forensic science and medical profiling. It is a sleek, modern procedural that trades traditional drama for raw suspense.

7. Chup: Revenge of the Artist – IMDb: 7.4

• Where to Watch: ZEE5, YouTube (Free)
• The Cast: Dulquer Salmaan, Sunny Deol, Shreya Dhanwanthary, Pooja Bhatt
• The Killer’s Pattern: Targetting prominent film critics and murdering them based on the exact flaws they pointed out in their movie reviews.

Can you imagine someone turning into a ruthless serial killer just because a critic gave their movie a 1-star rating? This film takes that wild, dark premise and runs with it.

Dulquer Salmaan plays a sweet, unassuming florist by day, but underneath that innocent face lies a deeply disturbed mind. If a critic wrote, “The director cut this movie into two uneven halves,” our killer literally cuts the critic in half. Sunny Deol steps in as a seasoned cop who has to wrap his head around this incredibly bizarre, creative pattern before another journalist gets slaughtered.

Chup movie is an absolute love letter to cinema lovers, blending a brutal crime investigation with a beautiful, haunting tribute to the legendary Guru Dutt. Dulquer Salmaan is brilliant at shifting between innocent and terrifying in a split second. It’s easily one of the most unique concepts in Indian thriller history.

6. Forensic (Malayalam) – IMDb: 6.8

• Where to Watch: YouTube (Free), Netflix
• The Cast: Tovino Thomas, Mamta Mohandas, Reba Monica John
• The Killer’s Pattern: Systematically abducting and murdering young girls from residential neighborhoods without leaving any physical struggle behind.

The story follows a highly skilled forensic science expert who has to rely entirely on DNA sequencing, blood splatter analysis, and microscopic evidence to track down a elusive psychopath. The plot keeps throwing curveballs, making you question every single character on screen. It treats the science of solving crimes with a lot of respect, making it feel very grounded.

If you spent your weekends watching international shows like CSI or Mindhunter, this scientific approach to a local mystery is going to feel amazing. It moves fast, focuses on the details, and avoids unnecessary dramatic filler.

5. Raman Raghav 2.0 / Psycho Raman – IMDb: 7.3

• Where to Watch: ZEE5, YouTube Free
• The Cast: Nawazuddin Siddiqui, Vicky Kaushal, Sobhita Dhulipala, Amruta Subhash
• The Killer’s Pattern: Targetting unsuspecting pavement-dwellers and slum residents, bludgeoning them with a heavy iron rod for no logical reason.

What happens when the cop chasing a serial killer is just as unhinged as the killer himself? This film answers that question in the darkest way possible. Directed by Anurag Kashyap and inspired by a real-life boogeyman who terrorized Mumbai in the 1960s, this is not your typical hero-versus-villain story.

Nawazuddin Siddiqui plays ‘Ramanna,’ a man whose casual, dead-eyed smile while talking about murder will make your skin crawl. Chasing him is a corrupt, drug-addict police officer played by Vicky Kaushal, who is fighting his own violent demons.

This movie is heavy, gritty, and definitely not for the faint of heart. It skips the shiny Bollywood glamour and dives straight into the gutter. Watch it for the unbelievable acting standoff between Nawazuddin and Vicky Kaushal—it’s raw, disturbing, and pure gold.

4. Memories (Malayalam) – IMDb: 8/10

• Where to Watch: JioHotstar, YouTube Free
• The Cast: Prithviraj Sukumaran, Meghana Raj, Mia George
• The Killer’s Pattern: Kidnapping specific targets and executing them using elaborate, ritualistic, and highly symbolic religious imagery.

Before he blew everyone’s minds with Drishyam, director Jeethu Joseph delivered this absolute masterclass in tension. The movie centers around an alcoholic police officer who has completely checked out of life after a personal tragedy. But when a serial killer begins staging highly theatrical, religious crime scenes across the city, the police department realizes only this broken man has the intellect to decode the killer’s mind.

It is a deeply human story about a man trying to claw his way out of depression while simultaneously tracking a literal monster. Prithviraj acts his heart out, and the eerie atmosphere will keep you hooked from start to finish.

3. Anjaam Pathiraa – IMDb: 7.9

• Where to Watch: Sun NXT, Aha
• The Cast: Kunchacko Boban, Sharaf U Dheen, Unnimaya Prasad, Jinu Joseph
• The Killer’s Pattern: Kidnapping on-duty police officers, brutally executing them, and carving out their hearts while leaving a theatrical mask behind.

Imagine a city where the police force—the very people meant to keep everyone safe—suddenly becomes the prey. That is the terrifying reality of Anjaam Pathiraa.

The story kicks into gear when a consulting criminologist gets dragged in to assist a panicked, clueless police department. The pacing of this film is relentless, moving like a bullet train. Every time the investigators think they are closing in on a lead, another body drops. The director keeps the tension at an absolute peak, and the killer’s signature style is genuinely unsettling.

This film is a pure adrenaline rush. The frantic background score and the clever camera work don’t give you a single second to look away from the screen. The final 20 minutes deliver a massive shock to the system that you won’t see coming.

2. Por Thozhil (Tamil) – IMDb: 8.0

• Where to Watch: SonyLIV
• The Cast: Sarath Kumar, Ashok Selvan, Nikhila Vimal, Nizhalgal Ravi
• The Killer’s Pattern: Stalking lone women in secluded, dark areas and strangling them without making a single sound.

If you appreciate a brilliant slow-burn investigation that treats the audience with respect, Por Thozhil is an absolute masterpiece. The chemistry between the two completely different cops keeps things engaging, and the climax features a twist that will make you sit up straight.

What makes this film so brilliant is how it handles the psychological profiling. The story focuses on a classic dynamic: an aggressive, old-school veteran cop paired with a book-smart rookie who literally trembles and panics during field operations. Together, they hunt an elusive killer who has suddenly active again after going completely dormant for years.

1. Ratsasan – IMDb: 8.3

• Where to Watch: JioHotstar
• The Cast: Vishnu Vishal, Amala Paul, Munishkanth,
• The Killer’s Pattern: Abducting young schoolgirls, brutally torturing them, and leaving behind a disturbing gift box with a mutilated doll.

Here it is—the undisputed king of Indian serial killer movies. The story follows an aspiring film director who has spent years researching psychopaths for a script, only to end up working as a sub-inspector due to family pressure. When a real-life monster named ‘Christopher’ starts terrorizing the city, this rookie cop has to use his movie research to guess the killer’s next move. It is a grueling, intense chess game where one wrong step costs an innocent life.

The way the director builds the mystery around Christopher’s identity and past is pure genius. It doesn’t rely on cheap jump scares; it relies on pure psychological dread.

In my opinion the background music (BGM) by Ghibran in this film is a literal masterpiece! That eerie, clicking, and haunting score gives you goosebumps even when nothing is happening on screen. It stays in your head long after the movie ends. If Ratsasan sits at the number one spot on every single thriller list, it is purely because of that unmatched combination of a tight screenplay and an spine-chilling BGM.
