Two ghosts, Harum and Scarum, are causing trouble for the captain of a ship. The captain calls on Snooper and Blabber to get rid of the ghosts and he will pay them ten thousand dollars. Snooper gladly accepts the case but Blabber is scared of ghosts.
When they arrive at the ship, Snooper sends Blabber on board and tells him to keep saying to himself that there are no such things as ghosts. Once on board, Harum and Scarum give Blabber the run-a-round and poor Blabber hits a brick wall, falls down into the hold of the ship, and is used as a badminton birdie by the ghosts before he is knocked off the ship. Snooper has had it and uses a bomb to get rid of the ghosts but winds up sinking the ship instead. They think that the ghosts are now gone until their car starts to chase them with no one at the wheel.
