My review

# Ratsasan Ending Explained and Full Movie Review

The Ratsasan ending explained in one line: the magician is not the mother, it is her son, and he has been playing the act the whole time. Ram Kumar's 2018 Tamil thriller sits at 7.4/10 on TMDB from 213 votes and 8.3/10 on IMDb from 62,000 ratings, with 95 percent on the Rotten Tomatoes Popcornmeter from fewer than 50 audience ratings and no Tomatometer reviews logged, all checked October 28, 2026. The claim worth arguing is that the twist chain works because every false answer is delivered by the procedure itself, not by a cheat, and that the film's one real weakness is what it chooses to make the true answer look like.

Spoiler-free verdict: An aspiring filmmaker turned reluctant sub inspector chases a serial killer who picks schoolgirls at magic shows. The investigation is genuinely procedural, the red herring is planted early and paid off cleanly, and the final act earns its violence. Rated 7.4 on TMDB, and it runs long. Full spoilers below.

What Ratsasan is about

Arun Kumar wants to direct films about psychopaths. Producers keep turning him down, family pressure wins, and he joins the Tamil Nadu Police as a sub inspector through his brother in law Doss, who is a circle inspector. He moves into the family house with his sister Kokila, Doss and their daughter Ammu, and the arrangement puts him next door to a teacher named Viji and her hearing and speech impaired niece Kayal.

The case arrives immediately. A fifteen year old girl named Samyuktha has been found murdered, and when a schoolgirl named Amudha is abducted, Arun sees the signature that nobody else is looking for: a mutilated left at the house. His superior, ACP Lakshmi, rejects the serial killer theory outright. Then Amudha's body is recovered, the forensic pathologist Dr Nandan confirms an identical modus operandi, and another hearing impaired student, Meera, is taken in the same pattern.

The pressure pushes the force toward an easy suspect. A tip exposes Inbaraj, a teacher at Ammu's school, as a paedophile. He admits to abusing students and denies the murders, tries to seize an officer's gun during an escape attempt, and Arun shoots him dead. That evening Ammu is abducted from her own birthday party and her body is found in a car boot. Arun is suspended, keeps working the file unofficially, and the film's engine starts: a piano melody recorded on Meera's recovered hearing aid traces to a touring magician, Annabella George, who had performed at every victim's school.

How the investigation builds

Ratsasan plays fair because it hides its solution inside legwork. The killer scouts victims on stage, so the film turns the school assembly circuit into a timeline. The hearing aid becomes evidence rather than sentiment. Surveillance on the magician's next chosen target fails in full view of the police, which tells the audience that the team's procedures are correct and still insufficient.

The performances support that discipline. Vishnu Vishal plays Arun as a man more comfortable with a case file than with a household, Amala Paul gives Viji the practical warmth that keeps the domestic thread from feeling like filler, Munishkanth's Doss is the only person who can order Arun around, and Suzane George's ACP Lakshmi is written as an obstacle with a point rather than as a villain. Ghibran's score does the heavy lifting in the tail, and San Lokesh's editing is why a film listed at 170 minutes on TMDB still moves like a chase. Ram Kumar, who wrote the screenplay as well as directing, has said the killer idea came from reading about the Russian serial murderer Alexander Spesivtsev, which explains why the film keeps reaching for procedure instead of for gore.

The chain runs in four links, and each one replaces a theory the audience has already accepted.

First, the misdirect. Inbaraj, the abusive teacher, is dead before the interval games begin, and Ammu is taken the same night, which kills the revenge reading of the case. Second, the false identity. The magician performing as Annabella George is treated by the police as the killer, and Arun traces the act to every victim's school. Third, the briefing. The retired officer Rajamanickam tells Arun that Annabella is an alias for Mary Fernandez, whose son Christopher has a condition that causes early ageing, who was a gifted pianist and magician, who was bullied and rejected by the only girl who befriended him, and whose mother murdered that girl before both mother and son were reported dead in an accident. Rajamanickam is killed before he can say more.

Fourth, the reversal. Working the retired officer's crime scene, Arun finds the evidence that flips the gender of the whole investigation: Mary did die in the accident, Christopher survived, and it has been Christopher performing as his late mother while carrying out the murders. He is not a ghost story, he is a working disguise. Christopher then moves to close the loose ends, injuring Viji and abducting Kayal, and killing both Venkat and Dr Nandan when they get in the way. Arun tracks him to a secluded hideout, wins a physically punishing fight, saves Kayal and kills Christopher. The media announces the end of the killings, and producers come to Arun with exactly the project he was begging for at the start: a film about a psychopath.

There is a fair objection to that solution, and The News Minute made it two weeks after release. Sowmya Rajendran argued that the film others its killer by giving him a genetic condition that has no link to violent behaviour, that the motive is delivered hurriedly, and that a murderer who looked like anyone else would have been more chilling, not less. She also noted that the two hearing impaired girls function mainly as clues. The critique lands, and it lands harder because the rest of the film is careful: the same review credits Ram Kumar with not handing the victory to the hero on a platter and calls the script cogent and new for Tamil cinema. The honest reading is that Ratsasan earns the twist mechanically and undermines it socially, and that the reveal is the moment the film trades a procedural about evidence for a melodrama about a monster.

What the critics said

Times of India rated Ratsasan 3.5 out of 5 on release, calling it a competent thriller for the most part and praising the tautness of the storytelling up to the interval. The News Minute's own review called it a good thriller that goes slightly overboard at the end, while noting that the visuals never become gratuitous, which is unusual for the psycho killer subgenre. The film's reputation has been built by audience ratings rather than by critics: 8.3 on IMDb from 62,000 ratings, 95 percent on the Rotten Tomatoes Popcornmeter, and no Tomatometer entry at all, which is part of why the conversation around this film lives on discussion boards instead of in magazines. It also travelled: the story was remade in Telugu as Rakshasudu in 2019 and in Hindi as Cuttputlli in 2022, and the makers only revealed in October 2018 that Saravanan played the killer in a dual role.

The verdict

Ratsasan is a well built case file with a solution it both needs and deserves. The TMDB rating of 7.4 from 213 votes and the IMDb rating of 8.3 from 62,000 ratings agree that the machinery is sound, and the disability critique explains why the ending divides people who otherwise agree. It is long, it is honest about its own procedure, and the twist chain holds up scene by scene.
