Gunaa (1991)

Guna (Kamalahasan) is a mentally disturbed youth whose mother Mannonmani (Varalakshmi) runs a brothel. He is obsessed with fantasies in which he casts himself as Siva, expecting Abirami to come and redeem him. Having been persuaded by his uncle to break into a temple, Guna sees the beautiful heiress Roshni (Roshni) and takes her to be Abirami, abducting her first to the brothel and, when he cannot stay there with her, to Kodaikanal. Roshni eventually realises that the madman who kidnapped her is really a kind person and she gets him to betray their whereabouts to the police. When the cops arrive, Roshni begs Guna to surrender, promising that she will take care of him. However, when her evil guardian kills her, Guna retaliates and kills the villain before leaping to his death off a bridge, holding his beloved ‘Abirami’ in his arms, thus proving that nothing can separate Siva from Abirami.
