Killer, rapist, drug dealer and all-round bad boy Arnie Dolan is back - and this time he's in a wheelchair.

But soon they encounter hostility both home and abroad as the Brexit debate rages and hooligans go on the rampage in Marseille. And as the mystery deepens it leads them to question everything they thought they knew...
