Peggy Mount and David Kossoff star as Ada and Alf Larkin in this big screen adaptation of one of the most popular situation comedies of the 1950s! After twenty-five years of faithful service to Belcher's Brewery, Alf Larkin reckons he's entitled to manage one of their pubs. Instead, all he gets for his years is an inscribed fountain pen! Leave it to his battleaxe of a wife Ada to set the brewery straight. Now the Larkins are off to manage the Earl Osborne - a remote country pub with a few problems. For a start it's a local with no locals! Business is as flat as Belcher's Best. The Larkins quickly manage to upset both the local constabulary and the Hooray Henrys from the local hunt and it seems like their tenancy may be short lived. But leave it to the Larkins to find unorthodox ways to 'drive up business'! What the Larkins don't know however, is that a main road is planned to be rerouted right past their pub - and they're sitting on a potential gold mine. A rival brewery has found this out - and will do anything to drive them away.
