Two strangers wake up in an underground bunker with no memory of where they are, how they got there, or anything about themselves. With no personal identification, no way to contact the outside world, and no one else to ask, they only have each other. To add to their torment, there is no way out, and their food supply is very limited. When their memories start coming back little by little with each passing day, and the urgency to get out before they starve to death increases, the strangers must piece together clues from their own recovered memories to get out of their cage. But, their captors have thought ahead, and their imprisonment is more complex than either of them imagined.
