New husband Adam reluctantly takes a job with state security in a totalitarian country, thus becoming a secret police agent. This "contract with the devil" helps secure a flat for the happy couple, as well as a prosperous future. However, he soon finds out that he too is under surveillance.

A short film set in a train compartment during a single train journey. You can't just stop a moving train, you can't jump off, you remain part of it until it brakes itself. The familiar world remains outside, enclosed, passing by the windows, only reflected in the train's windows. Inside, a new ecosystem is emerging, temporarily independent, bringing together random combinations of people. It's not difficult to intersect destinies; all you have to do is enter the compartment. You never know who has boarded.
