As described in a review in a film magazine,[5] Mad McCara (Morey), a sea captain, on the promise of marriage lures the widow Delaney (Madison) aboard his ship. A collision in the harbor gives him the chance to tell her that her son Jerry was drowned, though he sent him ashore. Years pass. McCara has tired of Mrs. Delaney, who has found shelter with the natives on the tropical isle of Taohing. Jerry (O'Brien), grown to manhood, conquers his adversary in a prize fight and, believing him dead, escapes by hiding on a ship bound for Taohing. He is discovered and Felicity (Dove), who is going to the tropics to paint pictures, becomes interested in him. To escape from being sent back home, he starts to swim ashore. Zelle (Cornwall), a young native woman, rescues him from a shark. McCara, now prosperous and using an assumed name, seeks to win Felicity, but she declares her love for Jerry. To save her from his disgrace, he pretends he does not love her. Felicity seeks shelter in McCara's home from the rain. To convince Jerry of Felicity's peril, his mother discloses her identity. Jerry arrives in time to save Felicity and avenge his mother. Returning home with his mother and Felicity to take his medicine, he learns that the man he thought he killed in the prize fight is still alive.
