A team of four criminals was active under the guidance of an invisible Boss, whom none had seen. Once a bank was looted. One of the criminals, Kedar, ran away with the loot, a sum of Twenty Lacs, deceiving his remaining three companions. Invisible Boss ordered the remaining three to find out Kedar so as to trace the sum of Twenty Lacs. They promised to do so.
Kedar went to Bombay and met his only sister Geeta. He told her that their days were changed and a luxurious life awaited them. Geeta was surprised and felt extremely happy. But the next morning she found her brother dead in a bath tub.
The other three had also reached Bombay. They thought, after Kedar's death, money must be with Geeta. They ransacked her home, but found nothing. Coming out, they met a new man, Ranjit, who knew all secrets about these criminals. He assured them that he could find out twenty lacs if he was also made a partner. A deal was agreed upon.
Now Ranjit wins the girl - Geeta. He once brings her to Rainbow Hotel where the remaining three are also having a separate room. One more mysterious character is Ruby, the owner of this Hotel.

She is about to be sentenced, when Ranjit puts and unfailing proof that Geeta was innocent and she is saved. Geeta is again perplexed. Why has Ranjit saved her? She again falls in love with him.
One day again, she finds Ranjit making love with a dancing girl Juliet and is very much shocked. Both of them drift apart once again. How is he mystery of the Twenty Lacs unravelled?
