The 28th Cardiff Sea Scouts, a troop formed of past-pupils of the De La Salle Preparatory School, Cardiff, are sailing from their base in the city's Bute East Dock to camp at Dale, Pembrokeshire. The Brenig Jones family visit twins Terence and Paul on Parents' Day and bring a cake to share. When it's all over, and the last bit of rubbish has been buried, a Curran's lorry takes all the equipment – and possibly some scouts - back home.
