Halloween Zombie Party

There's a Halloween party at Nick's house. His parents helped him prepare for it, laid out a table full of goodies and candy for the trick-or-treaters. But when his friends come over, one of them brings a really scary movie and they pop it in to watch, and not too much later they all began to realize that what's taking place on screen is actually happening in reality: the dead are rising from the graveyard down the block and coming after them! What sort of Halloween Party is this? A zombie one!
