The Redways prepare themselves for their very first holiday as a family, a borrowed caravan turns out to be more travel-stained than expected, and Sally decides to get rid of it so that they can stay in a hotel instead.
Persuaded to lower his career sights, Simon takes a job in a hardware store; Sally does her best to drum up trade, and very nearly gets him drummed out.
Sally's accused of mollycoddling when she discovers that Simon smokes, seeing him boozing and womanising in the pub makes things worse, and inviting his girl round for tea suggests that she has reason to be worried.
