Can Lee and Lucy’s friendship with Toby and Anna survive a long weekend in a damp cottage in the New Forest?

Lee is outraged that the twins have started sex education at school and resolves to teach them everything he knows about the facts of life before Miss Anstis corrupts them.

When Charlie’s school gets a bad Ofsted rating, Lee and Lucy start looking around for alternative schools. Despite Frank's protests, Geoffrey and Wendy offer to pay to send Charlie to a private school, which presents Lee and Lucy with a moral dilemma.

Lee decides to gatecrash Lucy's favourite television show and watch it with her. Lucy is not best pleased, especially when Lee can't remember the name of the leading actor.

Unable to convince Lucy that he didn’t smash her precious antique vase - an heirloom that belonged to her grandmother - Lee summons the family to a meeting to flush out the culprit.

Lucy takes the kids away to her parents while Lee stays in the house to oversee the building work in their kitchen. Unfortunately, the builder Lee has employed to do the job has an annoyingly relaxed attitude to deadlines.
