The film is based loosely around events in December 1995 that culminated in the murders of two top drug barons and their driver in Rettendon, Essex, UK.
On 6 December 1995, Rettendon was the scene of the murder of three drug dealers shot dead in a Range Rover down a small farm track.
Three of the gang, Pat Tate, Tony Tucker and Craig Rolfe, would eventually meet an abrupt and bloody end in December 1995, when they were shot to death in a Range Rover on a farm track in Rettendon, in what are known as the Rettendon Triple Murders.
