Tango

When Vincent (Richard Bohringer) discovers that his wife is cheating on him, he kills both her and her lover. Lucky for him, a jury decides he's innocent. The ruling judge (Philippe Noiret), however, is fairly certain of his guilt. Years later, the judge's nephew Paul (Thierry Lhermitte) is having his own troubles in love. So, remembering Vincent, the judge blackmails the murderer into joining him and his nephew on a road trip with a deadly mission: Find and kill Paul's wife.
