A very good film with a major surprise twist describes "A Killer Upstairs."
Tracy Nelson, unfortunately, is not very believable as the mother. You see absolutely no emotion shown. True, she believes that her emotionally disturbed son is innocent of murder, but at least she should act the part out at least by showing she is distraught.
Instead, she goes vigilante and gets lucky.
What saves this film is the surprise ending. The twist that occurs really makes sense when you think of it.
An old Bruce Boxleitner stars as a know-it-all detective. At least, he admits how wrong he was at the end.
Don't always lie for your children. A time will come when the police will not believe you.
