The luxury Space Liner was crusing the spacelanes sometime in the future. According to at least two of its rich passengers, Lord Nubbles and Anthrax, the cruise was rather boring. That was until Harpoon the Ghost pirate ordered Ghost of Moby-Dick to take hold of the Space Liner, stopping it in it's tracks and allowing Harpoon's men to board and enter the ship to rob it's rich passengers. Eventually, the Ghostbusters managed to free Moby-Dick and defeat Harpoon, ensuring that the passengers of the Space Liner all got their belongings returned to them.
