The movie is about a guy named Wild Bill who is out on parole after spending eight years in the klink. He doesn't have anywhere to go, so he goes to his old apartment, where he used to live with his two sons and their mother. But Wild Bill isn't named Wild Bill for being an angel and before his time in jail, he was quite the hooligan and lived a life of crime.
After he went to jail, his sons were left to fend for themselves after their mother abandoned them. When he comes back, they are 16 and 11. Dean (the oldest son) isn't happy to see him and doesn't want Bill to have anything to do with them. But eventually social services finds out the boys are on their own and unless Wild Bill plays the role of Dad, they will be forced to live in a foster home. Dean happily agrees to the situation as long as Wild Bill leaves them alone after social services gets off their case.
Over time, Wild Bill understands that if he wants to stay away from jail and keep his boys together, he has to live a clean life. At first, he does it because he has to, but over time, he does it because he chooses to and he begins to embrace his role as a real father. Things start going well until Wild Bill's old cronies try to force him back into the game and even attempt to get his youngest son involved as well. Wild Bill don't want none of that.
While it wasn't as good as the ratings make it out to be, it's still a pretty decent action-drama. The ending kind of came out of nowhere but it's not a bad movie for a bunch of Brits.
