Reeling from a traumatic tour of duty in Afghanistan, Joey (Jason Statham), an ex-Special Forces soldier, returns to London to face another kind of war: life on the streets as a damaged, homeless veteran. In an attempt to rehabilitate himself, Joey assumes another man's identity and seeks the aid of Sister Cristina (Agata Buzek), a young nun who works at an inner-city parish. But Joey's expert training as a soldier marks him as a valuable asset, and he soon finds himself caught in the dark web of London's criminal underworld. Struggling to keep hold of his integrity, Joey offers his profits to those who need it most. But when he learns his missing girlfriend was brutally murdered by a ruthless kingpin, he risks everything for bloody revenge, hurtling down a deadly path that promises to destroy him completely... or be his last and only hope at redemption.
