Dead Man Running
(2009)

Though having many setbacks including Mr. Thigo (Curtis "50 Cent" Jackson) actually impeding his attempts to pay his loan, Nick (Tamar Hassan) and Bing (Danny Dyer) come up with the $100,000 and deliver it to him on time.

Nick's Mother (Brenda Blethyn) kills her guard Johnny Sands and doesn't require rescuing.

Shortly after paying up, Thigo and his guard are murdered by a passing motorcyclist.

The man on the bike comes back to Nick and Bing and returns the money. It is revealed that Nick made a deal with the man he was supposed to kill; the man would kill Thigo and recover the money in exchange for getting to live.  Nick and Bing race off for a pint at the local pub.
