Maria Valverde, a young Spanish woman whose father has settled in the Philippines, arrives home from the convent where she received her education and is soon approached by Diablo Ramirez, a local plantation overseer who hopes to win her heart. Having met the handsome American army captain, Paul Winter, in Manila, Maria scorns Diablo's advances, and later, he is forcefully escorted from the house. Furious, Diablo organizes a group of rebels, who kill Maria's father and hold her a prisoner in her own home. When Captain Winter hears of the revolt, he rushes to Maria's aid but is himself captured. Reinforcements soon arrive from the American army post, and in the fighting, the house is set ablaze. Diablo is about to grab Maria when Captain Winter enters and shoots the rebel down. The Americans finally emerge victorious, and Maria wins her dashing captain.
