The Other (1952)

In the dead of night, an audacious cat burglar breaks into a lavish and isolated mansion in the affluent Athenian suburb of Psychiko, intent on striking it rich. Instead, he is shocked to discover that the wealthy owner of the villa, Chatzistavris, has decided to end his life, and what is even more surprising, the two men are like two peas in a pod. Under those circumstances, the thief comes up with a daring plan and plucks up the courage to use their striking resemblance to his advantage. Now, he poses as the deceased, eager to have a slice of the good life. But, will the "other" get away with deceit?
