Terry and June Medford live an ordinary, pleasant, middle-aged life in a typically middle-class suburb on the outskirts of London. Happily married, they are perfect foils for one another. Terry is full of schemes which have a habit of going horribly wrong when put into practice - not to mention his knack of innocently causing confusion. June is a charming lady who takes the consequences with patience and remarkable good humour, often managing to rescue the situation from utter chaos.
