'Businessman' Archie Daley, nephew of Arthur, is being leaned on by the deeply unpleasant Gold brothers, a pair of property developers, to bribe single mother Petra Bennett whose pub stands in the way of their planned local redevelopment scheme. Councillor Conway,a bent politician, also stands to gain by the scheme. Archie meets Jamie, a young taxi driver down on his luck and tries to rope him in to the plan. Jamie, however, has scruples and persuades Archie to concoct an elaborate scheme which will expose the villains to D.I. Murray.
