A (very) young John Simm, who went on to become the main character in the BBC series "Life On Mars", plays very convincingly a young man who's between a children's home and the community by staying in a halfway house.
Through his new job at a factory, Bill (Simm) gets to know and then stays with his foreman, Stuart Grady (Liam Cunningham), at his rented digs. When the snooping landlady asks for rent and sees the set-up of the two, she wants them out. Bill argues, she slaps him and is accidentally injured. To stop her phoning the police, Grady finishes her off.
The woman's husband is the prime suspect but that soon moves on to a man and woman, by Fitz's (Robbie Coltrane) deduction. What follows is a dangerous spree of violence by the two men and Fitz and his various, rather out-of-sorts colleagues, one of which is the very recognisable Ricky Tomlinson.
Fitz, as usual, puts his big psychological size tens into it at home as his wife tries to bring up their new baby. Fitz is as helpful, both practically and supportively as a chocolate teapot, with holes in it.
As ever, Paul Abbott's script is efficient, hard hitting and essential viewing.
