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.
