About the title
Former military man Dell works at a paper recycling company. His colleagues, his pregnant wife Petra, and her parents gather at the office to celebrate his birthday. Suddenly everyone receives an alert about a radiation leak in the city. Dell leads them into a secret bunker he built on the office grounds, three meters underground. Soon the equipment in the bunker breaks down, the exit is blocked, there's no contact with the outside world, there's only an hour's worth of oxygen left, and Petra goes into labor. Panic and distrust grow among those present, while dark secrets gradually come to light.
