Unfortunately, this story isn’t like a kind fairy tale. One day Liza disappears into the thicket. Now her older brother Sam and the local veterinarian, Phoebe, try to figure out what happened. A chain of coincidences leads them to an old cabin where a bloody prank awaits them, and the subsequent events will make them doubt their own sanity.
