Clubbing to Death (2008)

Set in the murky world of club culture, where Dench, a low life gangster runs the five biggest clubs in London, and supplies drugs to all of them. Everything seems to be going well until he gets greedy and decides to rip off his supplier by hijacking the next consignment before it reaches the UK. Trouble is the guy he's been dealing with forgot to mention that they belong to a psychotic American holed up in Morocco.
