The Firm (2009)

Centers on Dom, a young wannabe football casual who gets drawn into the charismatic but dangerous world of the firm's top boy, Bex. Accepted for his fast mouth and sense of humor, Dom soon becomes one of the boys.

But as Bex and his gang clash with rival firms across the country and the violence spirals out of control, Dom realizes he wants out--until he learns it's not that easy to simply walk away.
