A mezzanotte va la ronda del piacere (1975)

... making up is the most fun of all!

Tina is on trial for the murder of her lover, Gino. The violent nature of their relationship, revealed in the trial, seems to make obvious that she accidentally killed him during a fight. The lone female jury member compares her life to Tina's and, believing her to be innocent, sets out on her own to find a missing witness that can prove Tina's innocence.
