Sonny, a young surfer dude in Cornwall, is very worried about his family van. A former post van, it is held together with tape and has moss growing in the windows, and the once bright red outside has faded into an embarrassing pale pink colour! The last time the van went for an MOT, Sonny's mum was told that there were lots of problems under the bonnet. If they can't afford to get them fixed, they are in serious trouble - there are no bus routes where they live in rural Cornwall. Thankfully,Ali-Aand his team are on hand to give the old postal van a new lease of life.
