The film tells the story of the incredible metamorphosis of a petty clerk. His homeless life pushes him to play various roles, in which he gets interested and progressively entangled. The eagerly expected death, instead of rewarding his humiliating patience, suddenly stirs awake his sense of identity and his pride; while the false investigation, which has all the conclusive evidence to convict him, shows him the way to escape instead. Escape into absolute freedom, where moral principles are nothing but unnecessary attributes of a past age.
