In one night, in one room, three strangers–a thief, a retired policeman, and a delivery guy–are all present during the murder of the room’s occupant. As the trio tries to figure out this bizarre situation, the stakes are raised when they discover a huge pile of cash. They soon realize that the only way to get out alive is to unravel this mystery. What initially seems like a coincidence, turns out to be destined from the beginning.
