It's Halloween, and six friends are trick-or-treating together, trying to make the most memories because, after this fall, they're 'too old' for it. Their town LOVES holidays, especially Halloween, but they're strict on who can trick-or-treat. Around 10 pm, when the younger kids start heading home, the group decides to sneak away to the 'haunted fair' where they continue hanging out until it closes. After the fair closes, they decide to break into the town's 'genuine' haunted house and mess around at midnight. Here, they encounter a murder victim's ghost and help them get revenge on their murderer and bring them peace.
