The Radfords are faced with devastating news from their closest friends the Walkers when their 16-year-old daughter Sophie's cancer returns and an expensive trip to America looks like her only chance for treatment. Noel and Sue rally the troops to raise life-saving funds, kicking off with an urgent video appeal to their half a million followers on social media.

Noel and Sue are locked in a battle of wills to control their brood and their disagreements have Max and his 24/7 gaming at their centre. Younger brother Casper tries to entice Max into the garden, while Sue arranges for a fun half-term getaway, which goes disastrously wrong when Max plays his parents against each other and tricks Noel into believing he can stay at home. Sue rushes to Millie's aid when one-year-old Chester is proving a handful for Millie.
