A callow young traveler finds himself in a most peculiar predicament after crashing his car in the forest and being taken in by a strange family in this sinister fairy tale from second time director Yim Phil-Sung. Lee Eun-Soo was driving though the forest and talking on the phone with his pregnant girlfriend when he swerved to avoid running over road kill and winded up wrecking his car. Dragged from his car in a daze by a serene young woman, Lee is spirited to the "House of Happy Children" in the heart of the forest. Though the couple who owns the home and their three young children are more than accommodating, their injured guest begins to suspect that something is amiss when his cell phone loses all reception and he discovers the land line is out of order. The following morning, as Lee struggles in vain to locate his car, it gradually begins to dawn on him that these are no ordinary woods.
