A young man named JARED YOUNGERMAN awakens from a night of drinking to find he is tied to a chair in the middle of a deserted vacation cabin. He assumes it's a prank played on him by friends, but no one answers his calls and threats.
Soon, a weary-looking older man named SAM OLDERMAN enters the room. Jared assumes Sam is part of this unfunny prank. Ignoring Jared's pleading and cajoling, Sam goes about setting up a tray by Jared, laying newspaper over the tray and placing various tools on it. Jared furiously orders Sam to untie him or else; Sam responds by suddenly duct-taping Jared's mouth, grabbing a carpet knife off the tray, and severing two of Jared's fingers.
A cat-and-mouse game ensues with Sam leading Jared to think through various reasons he is in this situation, ranging from having crossed somebody to being the unfortunate random victim of a psycho killer. As the game continues, Jared is revealed not as an innocent victim in this bizarre game, but as a villain, one that Sam intends to wreak terrible vengeance upon for a crime Jared committed.
The important question for Jared to answer in the next harrowing hour is how to stay alive.
