Charlie's visit to Paris, ostensibly a vacation, is really a mission to investigate a bond-forgery racket. But his agent, apache dancer Nardi is killed before she can tell him much. The case, complicated by a false murder accusation for banker's daughter Yvette, climaxes with a strange journey through the Paris sewers.
