Dileep is an industrialist who runs a company named Minerva Exports & Imports. Despite his humble exterior, he has a dark side; he preys on nubile girls, has sex with them, and kills them. These proceedings are filmed and watched by his adoptive father and mentor, another deranged
woman-hater who, as with Dileep, had a disillusioning experience with women in his past. The man stays holed up in a far corner of Dileep's mansion, watching his adopted son carry out what he is too infirm to do. The victims are buried in Dileep's garden, and a red rose bush grows above each of them. Dileep meets a garment saleswoman, Sarada, and develops a romantic attraction for her. The romance proceeds, but conservative Sarada insists that Dileep must marry her if he wants a life with her. On their first night after marriage, Dileep rushes away to tackle a witness who had seen him taking Chitra, an employee of Minerva, to a restaurant; Chitra was subsequently killed by Dileep. After offering the witness, a waiter at the restaurant, some money, the waiter counters with a demand for more money to remain silent. Dileep kills him. Meanwhile, Sarada, who has been waiting for Dileep, notices several odd situations at home. Dileep's cat licks Sarada's blood after she accidentally cuts her finger. The cat chases her, and she ends up in a secret room where the entire story of Dileep is written on a wall by him. Dileep, born Muthu, was an orphan who was taken in to do odd jobs by a caring family. The daughter of the family begins to lust after Muthu and tries to seduce him, but her parents come home. The girl accuses Muthu of assaulting her, causing the parents to throw him out of the house. He ends up with another couple four days later and becomes their helper. When the husband leaves on a business trip, the wife goes out for the night and drunkenly brings home another man. The husband's flight is delayed, and he returns home to the scene where, overwhelmed with rage, he kills his wife. Muthu has a mental breakdown, encouraging the husband to stab her, and that all women are this way. This only endears him to his new father. In the present, a frightened Sarada rushes out and stumbles into the room of Dileep's adoptive father (whom Dileep had told her was mentally ill and not to be disturbed) and gets shocked seeing him watching films of Dileep having sex with girls and killing them. Sarada screams, catching his attention, but manages to lock him in his room. She tries to escape, but Dileep returns. When Dileep goes to park his car, Sarada rushes out of the house. After freeing his adoptive father and realising that his cover has been blown, Dileep chases Sarada. The chase culminates in a graveyard where Dileep accidentally gets impaled by a
cross. When he continues to chase Sarada while staggering, he is caught by the police. Dileep is imprisoned but becomes mentally imbalanced. He keeps chanting and writing Sarada's name on the wall as it is the only coherent thought that remains; all other memories have been erased from his mind. Sarada, instead of remarrying, regularly visits Dileep in jail, confident that their marriage will be saved and Dileep will be released soon. == Cast ==
