Teenagers Max and Uli are old friends and hang out together. When they discover a lonely phone booth, the crowning glory of the evening is clear: hotboxing! But the joint is hardly lit, when a police patrol turns up. Panicked, the boys barricade themselves in the phone booth. But the officers don’t even think about leaving. They lie in wait, they have time, they call for reinforcements. The escalation of the police quickly becomes a test of endurance for the trapped youths. And the more the night wears on, the more Max and Uli realize that they aren’t really friends any longer.
