But last year's bash was just a bit too much for little Jimmy to handle, and in order to ensure that never happens again he plots to do away with Halloween once and for all. However, Jimmy's little cousin Hannah lover her tricks and treats, and when she realizes that her favorite holiday is in danger she calls on all her ghoulish pals to come out and play.
