Gary's world is tipped upside down and thrown into utter turmoil when he discovers that a neighbour down his road is having a rival barbecue on the same day as his first barbecue of the year. To Gary this is out-and-out war and he sets about organising the biggest barbecue in history to win over the residents.

Meanwhile, Gary's childhood sweetheart Terri tries to befriend the aspirational Chloe Ferdinando by having microblading done but, when she cuts corners on the cost, the results are catastrophic. Big Gary is obsessed by a new online purchase, the World's Sharpest Knife, that can apparently cut through anything.

Gary's under-nines team are in the cup final, but his star player Abboussi is poached by Chelsea. Meanwhile, Terri is obsessed with a girls' night out she hasn't been invited to.
