All of them wind up at the decrepit sorcerer's ominously dark and creepy home; you know it's ominous because it has a graveyard surrounding it. Billy is the first to enter. In the dining room he finds presents and birthday decorations, and quickly concludes his parents are throwing a surprise party for him. Apparently Billy didn't notice that the house was ominously dark and creepy — and deserted. He peruses the presents and opens the biggest box, asking out loud if it's a bowling ball. Right, a bowling ball. The sorcerer's smiling head in the box isn't a bowling ball. Billy screams and runs out of the house, straight into a freshly dug grave. Scratch one really really dumb thirteen-year-old, though I still don't know why he was there in the first place.

Now back to our two cars filled with the bickering couples. Oh, and there's one guy solo: he's the one with the sock puppet, so you can draw your own conclusions as to why he's sitting alone in the back seat. He's the one on the left in the photo. They all wind up at the ominously creepy and dark mansion around the time Billy is coughing up dirt as the sorcerer's henchman, a purple-faced werewolf, buries him alive. They enter the mansion to party hardy. You know what happens to party people in horror movies, don't you?

I've not mentioned the annoying purple werewolf prowling around the woods all this time because I think you should experience that one for yourself. I'll just mention he likes to hold doors shut as the party people try to escape their soon-to-be rooms of doom in the mansion, but I don't want to get ahead of myself. It is pretty funny to watch, though, so I wanted to give you a head's up on it.

As horror movie luck would have it, the Sal Mineo look-alike of the bunch insists on breaking into a padlocked closet to find a corpse clutching a Ouija board. Carly, the quiet but Ouija-savvy girl of the bunch, knows exactly what to do with the planchette. They bicker  as Carly asks questions like "will we get out alive," and we cut to the sorcerer playing a game of chess, although he never seems to move any pieces. Apparently he needs the souls of people to revive his wife, who poisoned herself to get away from him. Ah ha! The plot starts peeking through. Enjoy it while it lasts because a peek is all you get.

Carly becomes possessed by the sorcerer and starts to go after the others. As they hustle out the front door, zombies crash the pajama party by popping up out of the graveyard. Naturally, everyone hustles back into the mansion while screaming hysterically. Then they start bickering some more and decide to split up. Zombies outside, a demon-possessed fiend on the inside, and they decide to split up. They actually take time to discuss the matter, too. Here's where you notice that the acting in no way attempts to mirror the adrenalin-rush terror befalling them. The three directors — yes, I said three — must have been on a coffee break during these scenes.
