When Shekhar came to Bombay for the treatment of his blind sister, he was shocked to know that his elder brother Keshav had been murdered by smugglers. He vowed to find out his brother's murderer and for this purpose went to see dancer Rita who was his brother's mistress. While returning from her place, he was waylaid by some gangsters and threatened that he should give up his inquires. This made him more determined. He was helped in his efforts by Rekha with whom he had fallen in love. One day Shekhar realised that Rekha really belonged to the group of smuggers and was moving with him to keep watch on his activities. His doubt turned into certainty when he found that a woman who could help him in solving the mystery was murdered by the smugglers before he could contact her. He decided to hand Rekha over to the police. But at the last moment the arrival of Rekha's Boss saved the situation. Rekha was a C.B.I. agent who had come with her Boss to unearth the anti-national plot which was being hatched by smugglers. Shekhar also learned form Rekha that Dr. Jagdish, a respected mental surgeon, was the head of the criminals. With Rekha's help Shekhar was able to reach Dr.jagdish's hidden head- quarters. There they found out that the doctor was trying to pass on military secrets to the enemy. But before they could inform the Boss, Rekha was kidnapped by the enemy. The doctor hypnotised her and ordered her to kill Shekhar during a dance in the night club.
