Edgar shows his true colours by running away during a break-in at the family home, leaving neighbour Johannes - who has designs on Wendy - to save the day. Jason goes travelling in Thailand and meets someone who looks exactly like him, while Eve accidentally summons the spirits of two great women to guide her.
Dusty surprises the family by bringing home a girl. An inflatable one. Wendy decides he needs a girlfriend so she hires him an escort without realising what the word really means. Meanwhile, Eve ODs on chocolate during a tour of Ken's confectionery factory. Ken has a crisis of conscience about manufacturing food that makes people fat and contemplates selling up to his arch-nemesis (and occasional squash partner) Richard Branson. Oh, and tiny aliens plan to take over the Earth...
Edgar decides it's time for his eldest son, Dusty, to finally make something of himself, but he's horrified when Dusty lands a job as a banker. Meanwhile, Jamie Oliver comes back from the future and his latest crusade is helping kids pass their exams one-by-one. He takes Jason and Eve on a trip through time, but naturally things don't go to plan...
After getting slightly annoyed at work, Edgar is committed to a mental home by Ken. To Edgar's surprise, the place is full of men who are hiding out from their demanding families, and he decides he quite likes it there. Until he realises the place isn't quite what it seems... Meanwhile, Dusty is bitten by a squirrel and decides this has given him superpowers. He starts fighting crime dressed as 'Squirrelman'. And at home, Jason tries to fill Edgar's shoes as the man of the house.
Eve is worried that she'll become boring and suburban like her parents, so when she meets a gypsy boy it's the perfect opportunity to rebel - and the two of them decide to get married. Her parents don't object as much as they might, though. Wendy's found an old bucket list, and they're working their way through it to prove they're still young at heart. And Ken is offered a knighthood - but will Sir Richard Branson allow it?
