A woman finds a VHS tape on her doorstep that shows a series of gruesome tales that could be real. But the true danger is the pumpkin-faced killer that's using the tape to find his next victim.

When Mary's boyfriend Ted invites her out to a fancy restaurant, she's convinced he's going to pop the question. But instead of getting hitched, Mary gets dumped. To cheer her up, Mary's friends take her to see a psychic who casts a spell to reconnect Mary with her ex-boyfriend. The only problem is... Mary didn't say which one. She bumps into her college boyfriend Patrick, and despite feeling he's completely wrong for her, she slowly falls for him again. Ted soon realizes his mistake and wants Mary back. Mary is torn between her two exes: Mr. Right on paper, and Mr. Right for her.

The city is quiet; the streets, deserted. It doesn't much feel like Halloween, and yet four young trick-or-treaters - a Ghost, a Devil, a Grim Reaper and a Witch - make their way through the night, door to door and house by house, gathering up an unlikely harvest of kindness amid the devastated wreckage of society's collapse. In a world where the only rule is that there are no rules anymore, it is perhaps a fitting irony that it should all come down to this... a simple choice between two starkly different options. The Last Halloween is here at last, and the time has come to make your choice. So, what will it be? Trick? Or treat?
