France 1809. The charming Captain Neuville is set to marry the naive Pauline when the war breaks out, forcing Neuville to depart for the battlefield. After not hearing from the captain for months, Pauline soon starts to become ill with worry, pushing her sister Elizabeth to write fake letters on behalf of Neuville thinking he would never come back. When Neuville finally returns home unexpectedly, he is welcomed in glory but in truth is a war deserter and an opportunistic coward. A suspicious Elizabeth is determined to expose the real Neuville and the two imposters are about to start a ruthless fight, conspiring against each other using the best tricks they can find.
