The Sister in Law

Robert Strong (John Savage), a singer-songwriter who has been traveling the country, makes a mistake when he goes to visit his brother, Edward (Will MacMillan), and gets involved with his bored sister-in-law, Joanna (Anne Saxon). Robert and his brother's mistress, Deborah Holt (Meridith Baer), try to help his brother get away from working in drug smuggling. It may or may not be a mistake, which turns out deadly.
