Apparently Sito and Ana are a happy couple. During a fight, Ana follows Sito to the lift. They argue on the way down, but as they reach the lobby, the lift returns to the 10th floor and the fight starts again. They are caught in a time loop. Sito is aware of this, but Ana is not. So, he must convince her of what's going on. Before they find a way out they'll have to fix their whole relationship.
