While on vacation in Jamaica with the Defenders, Kshin sees a ghost ship; however, no one believes him. Determined to get proof of the ship's existence, Kshin rows a dinghy out into the bay one night, and he not only finds the ship, but is taken on board by its ghost pirates!! Meanwhile our heroes are busy trying to figure out why Ming's roboships are in the area. Unbeknownst to them, the warlord is searching for Morgan's Compass, which he will use to turn the ghost pirates into his unconquerable slaves. On board the ship, the pirate captain tells Kshin that they have been searching for years for Morgan's Compass- the only object which can release them from their aimless wandering. Kshin offers help, and with the ghost first mate he goes ashore and returns with a sonic probe to locate the compass on the ocean floor. While Kshin is lowered into the water in a makeshift diving bell, Ming's roboships attempt to fire a freezebeam on the ship putting the ghosts in his power. However, the Defenders blow Ming's minions out of the sky! Kshin emerges with the compass, freeing the pirates and sending them on their way.
