Many passengers on the Shanghai Express are more concerned that the notorious Shanghai Lily is on board than the fact that a civil war is going on that may make the trip take more than three days. The British Army doctor, Donald Harvey, knew Lily before she became a famous "coaster." A fellow passenger defines a coaster as "a woman who lives by her wits along the China coast."

Lily saves him, but can she make him believe that she really hasn't changed from the woman he loved five years before?—Dale O'Connor
