It's a big weekend for the Jessops. Cherry and Robin's wedding is on the same day as Paul's police training graduation, Dean has big plans for Robin's best man speech, Maya is moving in with Amy, Sam's GCSEs are looming, and Rachel, despite her unusually low pain threshold, has decided to get a tattoo.

Rachel's competitive sister Penny and her husband Boyd are coming to stay in their massive new car, so Rachel is keen for the Jessops to project that they're happy and doing well. Meanwhile, Sue has sold her flat, Cherry is going wedding dress shopping, and Robin is seriously considering buying a disused munitions factory in Bulgaria.

Robin and Cherry's wedding approaches, but first there's the small matter of Robin's stag do. Rachel is quick to point out that the idea of stags and hens is very regressive. These days, a gender-neutral hag do is much more appropriate, and what's more, as his sister, she's known him longer than anyone. She should be best man. So begins Rachel's attempt at throwing Robin and Cherry what is billed as the best hag do on earth.

It's Valentine's Day, and various people have received anonymous cards and/or extravagantly large bunches of flowers. Naturally, suspicions run high in the Jessop household. Meanwhile, trainee police officer Paul has a brilliant plan to ingratiate himself with the CID lads. All he has to do is pretend to like football. And Robin's gearing himself up to propose to Cherry, if he can come up with a suitably grand romantic gesture.

Sue's moved in with the Jessops. She's lost no time installing herself into the local scene, starting by organising the street fayre with neighbour and pillar of the community, Edgar.

The street fayre hasn't been great, historically. It's mainly been a way for locals to eat cupcakes and complain about loft extensions. But Sue has bigger plans. She's getting in zorbs, a bring-and-buy sale, and a chap who can walk on his hands. It's going to be slaps. Meanwhile, aspiring copper Paul tries to solve a disgusting crime.

Life is changing for the Jessops. Sue is downsizing and having a big clear-out, Amy is back from Norway and pining for the fjords, and Rachel has started her new university course.

When Paul's old boat turns up in Sue's garage, he decides to take the family out on the water. Who knows, it might cheer Amy up a bit. Meanwhile, Rachel is keen to convince her new classmates that, despite being literally twice their age, she's one of them. She's planning to do this via the traditional art of the student drinking game.
