The real draw of this suspenseful drama was the yacht race and the motor boat chase, which included a hydroplane. No one cared much about the plot, but here it is anyway: Wealthy Lawrence Bradbury (a miscast Dustin Farnum) owns a transatlantic line which is being plagued by silk thieves. When he weds his fiancee, Constance (Ethel Gray Terry), he doesn't realize that her brother Ned (Maurice "Lefty" Flynn) is a detective who's on the case (as a matter of fact, the audience isn't apprised of this, either). Constance can't tell him because she is duty bound to keep Ned's profession secret. Bradbury comes to suspect that both his brother Jim (Fred Thomson) and Constance are part of the gang, but finally after a load of complications the truth comes out. The small role of Helen Palmer is one of Aileen Pringle's first appearances in a major studio film. In fact no one seemed to get the name of the future star of Three Weeks correct -- it ranges from Adele Pringle (Motion Picture News) to Eileen Pringle (Film Daily).
