It was a relief to Connie and Steve when their kindly neighbor "Uncle Dan" offered to take their ten-year-old son Timmy to his cabin in the mountains for the summer while Connie recovered from surgery. But the closer they came to Uncle Dan's cabin, the more unnerving Timmy found his friendly smile. Other children are staying at Uncle Dan's isolated cabin; Timmy can hear them screaming in the night. But when Timmy dares to peek through the keyhole of the forbidden locked room and sees the bloody fate that awaits Uncle Dan's guests, he realizes he has to escape...with the other children or without them.
