Bobby Bombata, a huge industrialist, and his girlfriend Devyani plan the theft of these diamonds along with Ranjit, a cold-blooded assassin. They hire Tora, an expert dacoit, to carry out the action. Tora double-crosses Bobby with the help of her brother Karan, but in the process gets killed. But she hides the diamond in a carriage, Victoria No.203. Raman, the driver of the carriage Victoria No. 203, is unaware of this and offers to help her, but the police level charges of murder and put him behind bars. A diamond expert Jimmy and two small-time-but-quite-old crooks, Raja and Rana, are also behind the diamonds. Raman's daughter Sara takes up the responsibility of freeing her father. Who gets possession of the diamond forms the rest of the story.
