 Army sergeant Nichols is a real bastard. Especially towards the black private Ken Marston. During a survival exercise on the moors Nichols starts shooting at Marston who jumps him in self-defense. The fight ends with Nichols falling off a rock and Marston makes a run for it believing he has killed his superior. He goes to Aidensfield to see an old friend Tom Sandford and befriends Tom s son Daniel. PC Rowan gets on his case when he breaks into a farm. Meanwhile the Sandfords are in trouble because Tom has died and the social services think his widow Helen is unstable and unable to take care of Daniel.
