All three feature length spin-offs from the popular TV series, which follows the fortunes of the workers in a Northern bus depot. In 'On the Buses' women drivers are to be introduced on the service and the lads aren't too happy about it. In 'Mutiny on the Buses' Stan Butler (Reg Varney) decides to marry Suzy, causing much consternation amongst the rest of the family who rely on Stan's money. Arthur implements a plan where he learns to drive a bus, while Stan blackmails the Depot Manager into giving him the new Special Tour Bus route - a move that can only lead to confusion and disaster. Whilst in 'Holiday on the Buses' Jack (Bob Grant) and Stan (Varney) are forced to find work driving tourbuses for a Welsh holiday camp after losing their jobs at the depot. Imagine their horror when they discover that Blakey (Stephen Lewis) is Camp Security Inspector!
