Lawler, a dishonest promoter, has Winton in his power, the latter believing that he has killed Yawkey, Lawler's partner. For his silence, Lawler demands the hand of Winton's daughter Josephine. Meanwhile, Billy Mountain, a man whom Lawler has swindled, arrives and, disguised by a heavy beard, interests his old enemy in a proposition. He invites Lawler on his yacht and makes him a prisoner. Josephine, fearing that Lawler will expose her father, accompanies them when they sail for a South American country involved in a revolution. When they land, Josephine frees Lawler, who joins the forces of the government. Billy and his partner, allied with the revolutionaries, plan an attack on the president and his forces. In the battle, Billy is captured and sentenced to death, but when the tide turns in favor of the revolutionaries, he escapes. With the appearance of Yawkey, Josephine is freed from Lawler's power and begins life anew with Billy.
