As a store manager on the busiest day of the year, the last thing you need is a bumbling 60-something re-trainee to turn up - surely it's a trap?

King of Fridges by Tim Firth follows Alan, assistant manager of electrical superstore, Rocket, who gets the chance to be store manager on a busy bank holiday whilst his boss is off work.
However, it seems his boss has laid a trap for Alan in the shape of Frank, played by Richard Wilson (One Foot in the Grave), a mid-sixties man on a re-training scheme for the redundant. Alan is faced with overseeing a man who knows nothing about electrical goods on the busiest day of the year.
The staff become convinced Frank is a spy sent from Head Office and Alan becomes paranoid that this bumbling idiot is in fact a skillful operator in disguise, assessing Alan's management potential. But events prove that Alan is in fact, tragically, just a bumbling idiot when he sets the store on fire. In this most extreme of situations, ultimately trapped in the letter "O" of "Rocket" on the shop roof, the two grow to embody different attitudes towards ambition and happiness in life.
