Pusher (2012)

Frank (Richard Coyle) may just be London’s most unlucky drug dealer. A handsome and charismatic small time criminal, he unwisely borrows money from a ruthless Serbian crime boss (Zlatko Buric) to finance what he naively believes to be a sure thing. But there are too many ways his plan can go wrong, and when nearly all of them do, Frank finds his life spiralling out of control. Scrambling to come up with the money, his actions grow increasingly despicable as his desperation mounts and his relationships with those around him begin to crumble.
