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.

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?

The Whitbury Leisure Centre is celebrating its first birthday with a series of special events. Meanwhile, Brittas's twin brother, Horatio, looks for advice about his vocation in the church.

Gordon Brittas is about to host a conference for leisure centre managers, and hopes to use the occasion to spread his dream of universal brotherhood. Laura has applied for a job elsewhere, and Helen Brittas is convinced disaster will befall the centre. She is not far wrong.

The staff stop talking to Gordon after he devises detailed personal fitness programmes for all of them.

Brittas stands accused of murdering several men. The evidence against him seems overwhelming. But could it be that he is, in fact, an unwitting hero?
