When the dismembered head of a young prostitute Cal has slept with is found in Cal's bed, the Beckett sons turn to their father to intercede. With no going back, the two families are plunged into a turf war.

Richie's mind deteriorates and he seeks help from former adversary and now respectable plastic surgeon Dr Seb Whiting.

Richie is diagnosed with a virulent form of early onset dementia. Marin's gang dumps the body of the decapitated girl in order to implicate Cal in her killing, forcing Cal into hiding.

Richie, having rescued a young woman from Vajkal's farmhouse, is on the run. Pursued by police and Marin's gang, the Becketts are holed up in Cal's fetid hideaway when Richie has a rare moment of clarity, but will it last long enough to save his family?
