Evelyn, a 42-year-old senior project manager, is working late in a completely deserted office on a Friday evening. Driven by her meticulous and controlling nature, she heads to the large, windowless supply closet in the building's central core to gather presentation binders for Monday morning. To her surprise, she finds Chris, a brazen 27-year-old subordinate, inside the closet stealing premium company paper for a personal project. As Evelyn steps fully into the room to reprimand him, the heavy, soundproofed fire door swings shut behind her. A loud click echoes through the cramped space as the notoriously faulty latch engages, locking them inside. The handle on the interior is broken. Neither Evelyn nor Chris brought their cell phones from their desks, and the weekend cleaning crew has been rescheduled. They are now completely trapped in the small, isolated closet together until Monday morning. While Chris assesses the predicament with calm, playful curiosity, Evelyn's carefully constructed professional world is rapidly shattering into visceral panic.
