Peter and Kitty love each other, but due to Peter's poverty, they are unable to marry each other. One day, Peter and Kitty accidentally overhear a conversation between one Mahesh Jetley and his paramour, that he is soon going to bump off his wife on a certain date. Peter and Kitty decide to foil this man's plans, not having seen either Mahesh or his paramour's face.
Hence, the lovers decide to do a little investigation on their own. However, each of their attack goes awry and they get saved from being arrested each time, just by a whisker. After discovering the amusing truth behind the whole affair, a bemused judge asks all the Jetley couples to decide the punishment for Peter and Kitty. However, all the couples forgive and thank the duo, as they did what anybody else would have done and that their "crime" has brought three marriages back from the brink of disaster.
