Gordon Brittas is trying to raise funds to buy a second trampoline so that Whitbury Leisure Centre can advertise "synchronised trampolining". To raise the money needed, Tim and Gavin are sitting in stocks having wet sponges thrown at them and Colin is attempting a marathon juggle. Brittas himself is on a sponsored silence, an idea suggested by his secretary Julie. Then a wealthy American turns up - but who is he?

Helen is about to give birth, and she wants everything to be just right. But events don't turn out quite as she expects. Meanwhile, Colin is having a strange recurring dream, and Gordon is preparing for the leisure centre's Elderly Week.

The manager of the Whitbury Leisure Centre, Gordon Brittas, invites Sebastian Coe to promote fitness in "Life Cycle Week."
