A tough, uncompromising tale about life-long friendship and hard choices, 'Capital Punishment' is a clash of ideals, deceit, betrayal, and danger set against the backdrop of "rogue" and "legit" sides of London's black cabs. Three ex-boxers who start out in life with the same chances - none - collide over major moral dilemmas. When Dave can't repay a loan to his friend Russell, his old buddy offers him a driving job that will earn him more than he can imagine. Once Dave realises he is actually running drugs, he wants out. But now he's a witness to murder, and leaving the business may cost him his life.
