Det. Sgt. Harry White thinks he can handle children, as he has five of his own - until he meets Mark Abbott. Mark is the son of a small time crim, Tommy, who taught him to never trust a cop. One morning Mark finds his father gone and the lounge room spattered with blood. The Homicide team gets little help from him, or from his alcoholic mother. The discovery of his dead father triggers off in Mark an outburst against his mother, whom he accuses of the murder. Notes: Fred 'Cul' Cullen appears as Det. Sgt. Jim Knight, standing in for John Stanton who was on sick leave and appeared in only one scene.
