Storyline

Jeremy and Julian Lewis, the "Lewis Twins", are two unruly brothers who terrorise the city of Swansea from the caravan park where they live with their family. When their father, Fatty, is injured while working on a roof for local kingpin Bryn Cartwright, they try in vain to claim compensation. Thus begins a campaign of terror, which local policemen Terry and Grayo are ill-equipped to prevent, involved as they are in a drugs deal with Cartwright.
