Movies like A Pure Formality

Onoff is a famous writer who hasn't published any new books for quite some time and has become a recluse. When he is picked up by the police one stormy night, without any identification, out of breath and running madly, without clear memory of recent events, the Inspector is suspicious. Through interrogatory dialectic, the head of this lonely, isolated, broken-down police station tries to establish what has happened, by delving into the mind of his writer-hero, and clearing up a mysterious killing.
