Captain Benedict kidnaps Hector Heathcote and his talking dog Winston, and he forces them to join his crew. Captain Benedict is on the trail of Moby Dick, the great white whale. Every time Hector loads the cannon, it rolls and points toward his own captain. Despite his incompetence and his seasickness, Hector not only captures the whale, but the pair also manages to get off the boat and turn Captain Benedict over to the law at the next port.
