For the co-pilot Tobias Ellis it begins as a normal working day and should actually only be a relaxed short-haul flight from Berlin to Paris. But soon it becomes the biggest nightmare of his life so far. Screams from the cabin let him guess, what is confirmed shortly afterwards: Terrorists want to take control of the plane in order to hijack it. But first they have to get in the tightly locked cockpit somehow. In order not to put his passengers at additional risk, Ellis enters into negotiations with the criminals. In the course of the extremely demanding discussions he must decide whether he should sacrifice the lives of a few to prevent a far greater catastrophe. The entire plot of the film is located exclusively in the cockpit of the plane.
