When the luckless Martin and Renato have the bright idea of starting up a guided coach tour of the M25, London's orbital motorway, they think they're on to a winner - but they soon discover they're on course for disaster.

When Marjorie's husband of 20 years dies of a brain tumour, she's hit financially as well as emotionally. The money she makes packing tights in a factory isn't enough to cover her rent, and her TV is repossessed. Soon after the funeral she meets Arnold, a wealthy pub landlord, who squires her to the local Conservative Club ball in an effort to cheer her up. Life with Arnold promises not only companionship but undreamt-of luxury, but Marjorie's friends and family do not necessarily approve.
