Bryn Cartwright, a wealthy roofing contractor, Rugby Club Chairman and local kingpin rules the roost until Fatty Lewis, a local handyman, falls off a ladder on a Cartwright job. Bryn refuses to pay compensation. The twins, Fattys wayward sons, devise a wickedly comic way of getting even and Bryn ends up paying dearly. Representing the thin blue line of the law are Terry and Greyo, two local policemen who employ their own dubious peacekeeping methods as events spiral out of control.
