this be essentially a remake of diagnosis murder minus victoria rowell and scott baio and charlie schlatter . dick be play a college professor who teach criminology 101 and can not even find his own classroom . barry be now a private eye and not relate to dick . this let barry shoot at guy speed away from him and which a cop can not do . barry still get the girl in the end . tracey needham portray the girl . she be the prime suspect and dick and barry believe she innocent and prove it . that all the spoiler you get . the end be sufficiently unexpected that you do not already know it half way through the movie . don not take it seriously . don not critique it . just sit back and enjoy dick and barry van dyke .
