"Bad" Ronald (Scott Jacoby) has been in hiding in a secret room ever since going off the deep end and killing a teenaged girl who'd made fun of him. Ronald's mother (Kim Hunter) helps her son to remain hidden, even when the house in which he is sequestered is rented by a family. As luck would have it, three of the family members are nubile young girls--perfect targets for the lonely, and looney, Ronald. In the original John Holbrook Vance novel on which this TV-movie is based, Ronald abducts, repeatedly rapes and ultimately kills two women. The video version of
Bad Ronald
is heavily laundered, but no less terrifying.
