The Bootleggers (1922)

José Fernand, leader of a gang of bootleggers, has designs on Helen Barnes, a shop girl who supports her delicate sister, and with the aid of Olive Wood, an adventuress, he lures the sisters to a supposed yachting trip. At sea, Helen is attacked by Fernand and dashes to the wireless operator for assistance, but a storm arises and an SOS is barely sent before the ship sinks. An ocean liner, picking up the call, starts for the rescue, and Jack Seville, Helen's sweetheart, a Navy aviator, comes by plane. The sisters and Fernand are cast up on an island and are there sheltered by a hermit, its only inhabitant. Seville and his pilot make a forced landing, and following a struggle between Seville and Fernand the entire party is rescued by the ocean liner.
