A poor but honest boy is in love with the daughter of a rich banker. He works faithfully at his trade as a street sweeper, until a strange twist of circumstance drops him into the very midst of a deep-dyed plot. Aboard an ocean liner two crafty Orientals seek to recover a valuable jewel stolen originally from an idol in their country. It is possessed and prized by the rich banker and by a mistake comes into the hands of our hero, who is chased about by the Orientals. He escapes them, but again meets his pursuers at a masked-ball, where they try to cast suspicion upon the hero for the theft of the jewel. But he triumphs, mostly by running away from danger, and wins the girl as a reward for returning the jewel to her father.
