The once-successful steel mills of Sheffield, South Yorkshire, have shut down and most of the staff have been made redundant. Former steelworkers Gary "Gaz" Schofield and Dave Horsefall have resorted to stealing scrap metal from the abandoned mills to sell. Gaz is facing trouble from his former wife Mandy and her boyfriend Barry over child support payments that he has failed to pay since losing his job. Gaz's son Nathan loves his father but wishes they could do more "normal stuff" in their time together.
