David's drunken rant has cost him his job and his marriage and he is living in a bed-sit when he receives an anonymous letter reading Happy Returns, leading him to wonder if Morton is still alive.

It takes a while for Andrew to ultimately get through to her. Chris has not rejoined the Army, staying in the town and, whilst he is cordial to David, his family is abusive . After discovering that his hotel room has been broken into David begins to suspect that Chris is not the outwardly friendly young man but a very troubled youngster and finds himself having to act, not only to avoid further bloodshed but to redeem himself for his past behaviour.
