While driving her car, Kamini (Shyama) runs over a young man (Dev Anand), who is seriously injured. She stops the car, and takes him to a hospital, where it takes several weeks for him to recover. Kamini visits him daily even while he is unconsious. When he recovers, she is attracted to him, and offers him employment with her dad Seth Mothumal's (Gope) business as a manager. After being discharged from the hospital, he takes up the employment offer, and is hired by Mothumal. He is also invited to dine at Mothumal's house by Kamini, and there he comes a mute maid-servant named Asha (Nimmi). Asha is attracted to him, and he also feels attracted towards her, little knowing that his past has come to re-visit him in her form, and not knowing the changes it will bring to his life.
On the day of his wedding, the life of a jailer is saved by an inmate during a prison break. Back in his cell the prisoner, Kishore, recounts his life story. He spent his childhood amidst the family of a wealthy thakur (landowner) and was treated like a son. But when the thakur died his jealous son relegated Kishore to the status of a servant. Kishore's romance with Asha, the young thakur's sister, earns him a beating. Rather than besmirch the family's honour by eloping, he agrees to leave on condition that he may return when he has become worthy of Asha's hand. He finds a job as a carnival daredevil, diving in flames from a high platform into a tank of fire. However, the carnival's lady owner wants thrills of a different kind and she isn't one to be trifled with -she killed and stuffed her cat to stop it running away..... When Kishore makes it clear that his heart lies elsewhere, Madame is not amused. She arranges for Kishore to be murdered. But the plan goes awry and Kishore ends up being wrongly convicted of her murder and thus finds himself in jail. Both the jailer and his fellow inmates sympathise with him. The jailer wants him to meet his new bride whilst his fellows work on a plan to get him released. One of these is a good idea, the other is not.
Ratan and Chaman are twins brothers who love the same girl, Meera. During a fair, all three are separated. While Chaman and Meera are found, Ratan is untraceable. Years later, Chaman is no longer attracted to Meera, but in a dancing girl named Rasily, while Meera awaits word of her childhood sweetheart Ratan, who she feels is still alive. Then the unexpected happens, Chaman gets into a fight with another man, killing him, and is on the run from the police. Misunderstandings are clarified, and the law declares this to be an accidental death, and as a result Chaman returns. But this is not the same Chaman any more. For one thing, he has lost interest in Rasily, and is more interested in Meera - could it be that Ratan has returned in place of Chaman? If so, what has happened to Chaman?
