Watch Best Kept Secrets (1984) Official Trailer

Blaise Dietz (Patty Duke Astin) plays the wife of police officer Blaise Dietz (Frederic Forrest), who wants to join a special investigative unit. Forrest is denied this position on the basis of information concerning his wife. The information, which reveals a dicey extramarital affair, was culled from a department surveillance file that was supposed to have been destroyed by court order. Blaise battles through legal channels to expose the police force's illegal actions, even as she and her husband suffer the innuendoes and cold shoulders from his fellow officers.
