"The Shortcut" (2009)
In the basement, Mark and Taylor discover an old man named Benjamin shackled to a large wheel by a chain that is padlocked around his neck. Benjamin pleads for them to help him before the other elderly man arrives back home. Lisa, Mark and Taylor take Benjamin and depart the house, but Benjamin is still bound. As they reach the shortcut, the chain restricts him from moving farther. Taylor grabs a sledgehammer to break the chain while Benjamin and Mark hold the chain tight. As Taylor swings the sledgehammer, Benjamin yanks the chain, bringing Mark's hand in line with the swing, horribly disfiguring it.
