A man gets sixteen years for smuggling drugs into Italy. Guerrieri takes on the appeal, discovers the accused was a neo-Fascist thug, and ends up in bed with his beautiful half-Japanese wife...the gnawing boredom of routine.

When no lawyer accepts to represent Marina in her attempt to bring her boyfriend to trial for assault and battery, Guerrieri takes the case. No witnesses willing to testify and a hostile judge: just his kind of case. Doesn't hurt that he's attracted to Sister Maria, the young woman protecting Marina, who shares his love for martial arts.
