On a train from Kurdapur to Bombay, identical twin brothers, Brits David and Phillip Bartlett, who have been living in India, accidentally meet. The two, who do not get along, both seem to be running away. David is up front about the fact that he and his wife, Mary, have had yet another argument and have split. Phillip is initially a little more secretive about the reason for his trip to Bombay. David eventually learns that Phillip has embezzled money from the bank where he works. Both sense an opportunity, David who wants to blackmail Phillip for the nefarious act, while Phillip wants to take on David's identity to save himself from being caught for embezzlement. If Phillip is successful, he may have difficulty in running away from the unknowns in David's life.
