David Brandon, born in the Canadian Northwest, is taken to England when his father, Albert, inherits a title and a fortune. Later, as a youth, when he fails to win the girl he loves, David returns to Canada. Joining the Mounted Police, he aids in tracking some bootleggers. Jackie, his childhood sweetheart, warning him of an attempt to frame him, is kidnapped and held prisoner. David learns of her plight through an old woman (actually his mother, whom he had previously thought dead) who befriends him. Following a long chase and an undersea fight, he rescues Jackie and discovers the identity of the woman his father had deserted years before.—AFI
