Undead

On a ski trip the bus comes to a stop at a restaurant. Everyone gets off, except Bobby, the new girl and rebel Smitty. Hours pass, snow piles up, and the sun goes down. Finally the other kids stumble back. But they've changed, they're zombies. The wheels on the bus better go round and round fast, because that's the only thing keeping Bobby and Smitty from becoming their classmates' next meal.
