Jenna is the only daughter of Manuel, keeper of the lighthouse. She loves Tony, the hero of the fishing fleet. But Pedro is determined that Tony shall not possess Jenna. Tony presents Jenna with a silk scarf. Tony puts to sea in the face of a threatening storm. Pedro stays ashore and plans a deadly act against Tony. The storm breaks over the sea with terrible fury. At its height Pedro forces his way to the lighthouse, overcomes the resistance of Manuel and Jenna, and extinguishes the light. While old Manuel lies senseless on the floor, Pedro is in the tower above. Jenna stretches her scarf across the tower stairs, so that he trips and falls heavily as he descends. While he lies unconscious Jenna runs up to the light tower and relights the beacon, so that Tony is saved. Pedro meets a terrible end at the moment that Tony and Jenna seal their love.
