It's All Hallows Eve, so Peter and the Lost Boys are playing tons of pranks on the pirates. One of those pranks was stealing the pirates' lantern. This revives the Jack O Lantern ghost, who gets Smee to steal the lantern back from Peter. The ghost then summons ghosts, witches, and goblins from the volcano to wreck havoc all over the island. At first Hook and the crew think Smee is a deserter and hunt him down, but when they learn about the ghost they realize their mistake. The pirates and the Lost Boys must team up if they're to reclaim the lantern before Neverland is completely overrun by the undead! (thetvdb.com)
