Four women are trapped in a house with many doors. At first they don’t realize they are trapped and celebrate some holiday by exchanging gifts. When they go to find the gifts in other rooms though, they are met with many traps. The rooms are apparently unending. Most contain nothing at all, some hallways to more rooms, and a few monsters and deadly forces.
One girl finds the owner of the house who implies he is the Devil and bets the girls cannot find their way out. The other three find a creature made of seaweed that attacks them.
