Chattfield Bruce, In China to buy goods for an American firm, Chattfield Bruce is impressed by the conduct of Wong Lee, a pirate who plies his occupation solely for the purpose of giving to the poor the rice and treasures he steals from the rich. The Chinese pirate has been particularly active in his depredations against the rich shipowner, Fong Wo Chong. The merchant offers a reward for the pirate's apprehension and Caglioni, one of Wong Lee's henchmen, betrays his master. Bruce discovers the fact in time to notify Wong Lee. In gratitude, the pirate gives the American a ring guaranteed to give the wearer the allegiance of Chinamen in any part of the world. When Bruce returns to America he resumes his position in good society and becomes noted for his generosity to the poor. He is reputed to receive large incomes from his estates, but in reality Bruce has adopted the Wong Lee method of equaling the wealth of the world. Wong Lee's son comes to New York and opens a store in Chinatown, as the base of operations for Bruce's activities. To provide himself with an occupation that will give him wider scope for his practicing his peculiar style of philanthropy, Bruce retains his position with Nathan Goldberg, a merchant with social aspirations for his daughter. Marjorie Woods, a schoolmate of Miss Goldberg, arrives from Europe with Sir Archibald Bamford, a bankrupt nobleman, following closely in her wake, his eyes upon the fortune Miss Woods is reputed to possess. Goldberg has purchased for his daughter a string of pearls of great value. There is arranged a lawn party by the Goldbergs as a welcome to Marjorie. To this the Goldbergs invite everybody listed in the social register. Goldberg hires detectives to guard the pearls. Unknown to Bruce, Wong Lee's betrayer has come to America and Caglioni is now a member of the local detective force and in charge of the arrangements for protecting the Goldberg pearls. Bruce has arranged that Wong Lee's son shall act as one of the waiters at the garden party. At an opportune time Bruce gets the Goldberg pearls into his hands, and clumsily drops them to the ground, when, in picking them up, the young Chinese man substitutes worthless imitations for the string of expensive pearls and slips the real ones into his wide sleeve. The Goldberg pearls were intended to be subsequently disposed of through the Chinese man's source of distribution, Bruce to use the proceeds to build a hospital for the infirm and afflicted poor. Bruce and Marjorie have been invited to spend the night at the Goldbergs. Bruce wanders into the Goldberg drawing room in time to witness the burglary of the wall-safe where Goldberg deposited the spurious pearls for safekeeping. Caglioni is concerned in the burglary and has also recognized Bruce as the man who, in China, warned Wong Lee of his danger. Marjorie, restless, wanders into the drawing room and is another witness to the burglary. The girl is mystified by Bruce's strange conduct. Bruce confesses to Marjorie that he is a social buccaneer. Miss Woods induces him to abandon his peculiar pastime and become a good, dutiful husband.
