A Question of Silence (1982)

Housewife Christine M. tries to shoplift some merchandise from a boutique in a shopping mall but is caught by the male shopkeeper. Christine and two other customers, waitress Annie and secretary Anna, beat the man to death, witnessed by a large group of other female shoppers. They are tried with murder and deny the plea of insanity that the male prosecutor and judges assume they should plead. The female criminal psychiatrist assigned to ascertain their level of sanity comes to identify with the women's situations and concludes that they are not insane but have been driven to murder by the strain of living in a patriarchy.
