At the expiration of their prison term, Sampson and Wilson separate; Sampson determined to lead an honest life in future, Wilson to follow his old life. Some years later Sampson (now a prominent businessman) is accompanying his daughter. Betty, home on the boat from an art school abroad. On board is Wilson, a dangerous and much-wanted smuggler. Conners, a Secret Service man, is on his trail. On a previous trip Conners saved Betty (then traveling alone) from the unwelcome attentions of Wilson, and they are attracted to each other. Wilson sees Sampson, recognizes him, and on the threat of exposing his past, forces him to agree to carry in the diamonds he is now carrying concealed in a hollow cane. Sampson agrees and Wilson suggests that he sew them into the top of Betty's hat. Conners oversees the act. He plans to save Sampson and the girl and still perform his duty and get Wilson and the gems. He takes the gems and waits until the boat lands. He then hires a porter to upset Wilson, who drops his cane in his fall. Conners gets hold of it and quickly slips the gems into it and lays it back on the deck, from where Wilson picks it up and strolls off the boat, confident that his diamonds are safely off in Betty's hat. He is searched on the dock and, much to his surprise, the gems are found in his cane. Conners later marries Betty.
