Three young people head to a remote holiday apartment complex, left vacant during the off-season. They are Alice, her best friend Lizzy, and Lizzy's perverted boyfriend Carl. Things quickly take a turn for the worst, as the group gets trapped in one of the high-floor apartments, unable to escape. No one knows they are there. They have no way to contact the outside world. Food and water grow scarce. Desperation sinks in. Is this all just a series of unfortunate events, or is there something supernatural behind it?
