Ai margini della metropoli
Cult feature-length movie by the talented Lizzani, released the same year of Siegel's Count The Hours a film with which curiously shares noir plot-elements. A middle-class lawyer (Girotti) is not sure whether to accept to be the defendant of a lower-class worker (Jourdan) wrongly accused of a murder and whose position is very compromised (in this case he is accused to have killed his former lover)
