What could possibly go wrong this time for our couple with: Geoffrey (very reluctantly) trusting Lee and Lucy to help tidy his house while on holiday; Lucy thinking she's stumbled on the perfect birthday event for Lee... a trip to a slightly sinister Escape Room; a prized keyring going missing, leading to friendships being put to the test – not to mention a truly terrifying insight into Toby and Anna's marriage; deciding to introduce a pet into the house to teach "the kids" to be responsible; Lee and Lucy becoming addicted to the latest TV boxset and desperately trying to wriggle out of long-standing plans; the local Lollipop Man getting in the way of Lucy's goal to make the family healthier; and Lucy considering that perhaps breast augmentation is the way to reconnect with the femininity she felt in her youth.
