Onoff is a world-famous writer who has not published a new book for some time and increasingly revels in his reclusive personality. One night during a storm he is picked up by the police without any kind of identification or memory of recent events, perplexing the authorities. During the interrogation, a literature-loving inspector tries to work out what happened during that afternoon and immerses himself in the mind of his admired author to reveal a mysterious crime. Inspired by the film A Pure Formality (1994), by Giuseppe Tornatore.—(Official Summary - Rio de Janeiro International Film Festival)
