A hardened rusty nail

Absolutely zero expectations. In fact, thought of getting a tough guy picture of some Steven Seagal or Vin Diesel wanna-be. Well yeah, there's a tough guy Cain (Scott Adkins), an incarcerated boxer, but it's of a bit different nature. For one, it's a British movie and that only gives it a bit more edge and it's a bit more straight-forward bashing of heads. This boxer dude has a 20,000 pounds price on his head, so with prisonful of hardeded criminals, he has his hands full and somehow gets his way of revenge outside the prison as well. Kind of cool.
