That indefatigable old trouper Hobart Bosworth topped the cast of the Columbia "B"-plus feature The Blood Ship. The villain of the piece is Captain Swope (Walter James), a "Wolf Larsen" type who shanghais his crewmen, beats them into submission, then allows them to jump ship so he won't have to pay their wages. Swope meets his match when old sea dog Newman (Hobart Bosworth) signs on board. Having searched lo these many years for the man who double-crossed him, broke up his happy home, and framed him on a murder charge, Newman finally catches up with the no-good rat -- who, of course, is none other than our old friend Swope. After rescuing the hero (Richard Arlen) and heroine (Jacqueline Logan) from Swope's clutches, Newman metes out a horrible retribution.
