Willesden Confidential(2005)

Dangerous Davies investigates the death of Geoff Fallon, a stock car driver who was killed during a race at the local stadium when his car exploded due to a leaky fuel line. There seemed to be a considerable animosity with his brother, also a stock car driver, but it turns that Fallon was convicted of killing a child with his car some years previously and the dead child's older brother was working at the stadium on the night in question. When a second person is killed, Davies determines that the case is far more complex than originally thought. Meanwhile, all of the officers at the local station are under investigation when information is leaked to the press.
