Exsanguination (2011)

While attempting to change a flat tire on his van in a dimly lit parking lot, a man is brutally attacked from behind and injected in the neck with a hypodermic needle. Hours later, the man regains consciousness and finds himself inside a small dark room shackled to the floor with both wrists slashed just a few feet away from a complete stranger in the exact same predicament. Gradually hemorrhaging, the two men get to know one another as they ponder their deadly circumstance and try to keep each other awake for fear of becoming comatose.
