Stuttering shopkeeper Albert Arkwright, assisted by his much put-upon nephew Granville, runs the corner shop in a Doncaster suburb, boasting that it's open all hours. When not pursuing Gladys Emmanuel, the district nurse who lives opposite the shop, Arkwright is ever on the lookout to save money, such as buying a load of fire-damaged tinned food. Unfortunately, the damage means that all the labels have come off so nobody knows exactly what they're meant to be buying.
