Gopal is a rich businessman
en route to India from Singapore on a
cruise ship. He meets Latha, another traveller who has been accompanied by her father Ramadurai. Gopal and Latha find that they like each other, so Gopal invites them to stay at his mansion in
Ooty, which they accept. One day, Latha discovers that Gopal becomes agitated whenever he sees an onrushing train and demands to know why. He explains that the reason behind this is his first wife. Gopal recalls that, after losing his mother, in sorrow he had been wandering aimlessly at Singapore. He fell in love with Chitra, a nightclub singer, and they married in the presence of her brother Raju. But to Gopal's dismay, Chitra always came home inebriated, and despite his repeated requests, had little respect for tradition and family values. When Chitra showed up drunk for Gopal's birthday party, he tried to control her, but she refused to co-operate; Gopal's father died of a heart attack after seeing Chitra's behaviour. Irritated by Gopal, Chitra later tried to leave him; he caught up and begged her to change her decision, but Chitra berated him for controlling her, and he slapped her. Later that night, he heard that Chitra committed suicide on a railway track, and this hurts him a lot. Latha sympathises with Gopal and accepts his love. The engagement of Gopal and Latha is fixed. While the reception is being held at Gopal's mansion, a woman claiming to be Chitra arrives, accompanied by her uncle Rangan. Gopal's engagement with Latha is cancelled after Rangan convinces everyone that the woman is indeed Chitra. Gopal says she is an impostor and shows Chitra's death certificate as proof, but Rangan reads in the certificate that though the corpse was disfigured beyond recognition, Gopal insisted that it was Chitra so it was declared to be her. Rangan's actions convince Gopal's police officer friend Kumar, although Gopal is adamant that his wife is dead. "Chitra" and Rangan become disruptive and Gopal gets frustrated, fearing that Latha might leave him because his "wife" has turned up. After many failed attempts to expose the impostor, Gopal reveals the truth to everyone: when he slapped Chitra, not knowing she was suffering from a heart condition, she died immediately. Gopal realised that he had inadvertently killed his wife. To avoid arrest, and safeguard the honour of his family, he manipulated the murder to appear like a suicide on a railway track and fabricated the necessary evidence to show that Chitra committed suicide. With everyone believing his story, Gopal orders Kumar to arrest the Chitra impostor. However, Latha reveals herself as a police officer investigating Chitra's death based on the complaint filed by Raju, who suspected she could not have committed suicide. Ramadurai is Latha's senior posing as her father, Rangan is the local investigating officer, and the Chitra impostor is Rangan's aide, Sarasa. Together, they staged an entrapment to get the killer's confession because there was no clinching evidence. Latha confesses to a dejected Gopal that though she initially pretended to love him, his good nature impressed her and she truly loves him; she promises that she will wait for him till he returns after completing his jail term. Gopal is relieved, but is still arrested. == Cast ==
