When a Man Sees Red (1917)

Returning home to find that his sister has died after being abducted and violated by an unscrupulous man, sailor Larry Smith ships out as mate with Captain Sutton. After an altercation with the captain, Larry leaves the ship at a South Sea port where he meets and falls in love with Violet North, a woman of questionable reputation who is the mistress of millionaire Lewis. Larry proposes, but Violet sails with Lewis anyway. Sutton also sets sail, leaving behind inveterate drunk Logan, who informs Larry that Sutton was the man responsible for his sister's death. Sometime later, Lewis' yacht is wrecked and Violet is cast upon an island. Sutton picks her up and tries to sell her to the natives as punishment for resisting his advances, but Larry rescues her and kills Sutton. His sister thus avenged, Larry marries Violet and settles down.
