For most of us in Britain, the Mafia seems as distant as the characters in "Goodfellas," "Gomorrah," or "The Godfather" trilogy. However, the truth is far more sinister.

Drawing from his groundbreaking Sky HISTORY series, renowned journalist and fearless investigator Ross Kemp delves into the depths of the Mafia's influence within the UK - unveiling the Mafia bosses, capos, and hitmen who work next door, from caravan parks to shoe shops, cafes to newsagents.

Travelling from London to New York, Philadelphia, Miami, Colombia, Spain, and Italy before returning to Britain again, Ross embarks on an epic odyssey to trace the story of the Mafia over the last 100 years - revealing a globalized web of connections that have enabled the Mob to quietly, yet effectively, infiltrate the heart of Britain's underworld, and shape our society from within.
