The Blood Ship (movie, 1927)

A disgraced sea captain signs on as a crewman on a cargo ship. He discovers that the vessel is captained by the very man who stole his ship, a sadistic brute who also took the former captain's wife and daughter. The ship's crew is composed mostly of sailors who were shanghai'ed aboard and are kept in line by the brutal captain and his even more fearsome first mate. The captain and one of his fellow crewmen--who has fallen in love with the man's daughter, who now belongs to the brutal captain--try to unite the crew to end the brutal reign of the captain and his henchman.
