Spring

Milky, Woody, Lol and the gang are all reunited in the classic era of 1990s rave culture, Following on from the events of 1988, Woody and Lol are back together and have a little baby, Jimmy. Lol has a job running the local school kitchen with Chrissie, Kelly and Trev working as dinnerladies, while Woody stays at home with the kids.

Gadget, Harvey, Kelly, Trev and Shaun are all following the Madchester rave scene, smoking cannabis in bongs and taking whatever drugs they have, usually provided by Harvey who appears to have become a low-level dealer on the estate.

After a conversation with Cynthia about the events of '88, Shaun goes to find Smell who dumped him in '88 for cheating on her with Fay after the Christmas production at college. When he finally managed to find her ending a day at her new college course, Shaun tells Smell he has missed her and invites her to a Manchester-themed discothèque at the town hall but Smell is reluctant to go, then tells him she has met someone else, which hits him hard, prompting his crying.

Meanwhile, Woody and Lol have gone round to Woody's parents' house where there is a certain surprise for Woody, after seeing that his ex – Jennifer – is staying over, after a row with her parents. A certain blast from the past bursts out of the cupboard... Mr Squires, Woody's old boss. He offers Woody a partnership but Woody gets upset and angry because he doesn't want to end up like his dad and then an argument erupts.

Later Shaun is seen round at Harvey and Gadget's flat taking bong hits. Shaun tells the lads what happened when he saw Smell and then Harvey jokes about it, impersonating Smell and cheering up Shaun.

Afterwards Woody, Lol and the gang are all round at Lol's mums talking about the disco, then Kelly and Trev persuade Lol to attend so the girls get ready and head off. Shaun, Harvey and Gadget are heading into the disco when Shaun suddenly starts suffering with dizziness and nausea, a reaction to the bong hits he previously took, but Harvey gives him some speed to perk him up for the night.

The girls meet the lads in the disco and "Fools Gold" starts to play and everybody gets pumped up and raves. After the disco a Goth-like lad called Harrison goes over to Shaun to tell him that he is Smell's boyfriend, and he is sorry Smell can't make it, but then Shaun, feeling disrespected in front of his mates, over-reacts and a skirmish occurs.

After things have calmed down everyone goes home and we see Woody asleep and Lol getting ready to go to bed.

Summer

Shaun, Harvey, Gadget, Kelly and Trev all pack into a small car, venturing into the countryside in search of a rave. On the way they meet Flip and Higgy, whose car has broken down, so all seven squeeze into one car. After a long day trying to find their intended venue, they give up and begin to camp out in the woods for the night. In the distance, they hear the sound of drums and assume it's the rave they've been trying to find. Walking down into a field they stumble upon a commune of new-age travellers and spontaneously join their party. Shaun finds comfort with an attractive older lady, whilst Kelly, already drunk on alcohol and high on Ecstasy, is encouraged by three older men to smoke drugs before having sex with them in a trailer. After waking, whilst watching the sunrise, a tearful Kelly confides in Gadget "I'm a fucking slag Gadget...I just do what I fucking want, Gadge, that's the fucking problem".

Lol, Woody and Milky stay at home, spending the afternoon having a barbecue in their front garden. When the phone rings in the evening, Lol says it is her mother and takes the call in another room. She later tells Woody that it wasn't her mother, but it was Combo, who is about to be released from prison and needs a place to stay.

Autumn

Lol and Woody invite everyone round to their house for Sunday dinner. After the meal, they inform everyone that it wasn't Combo who killed Mick, but Lol. Lol also tells her sister Kelly that Mick raped Trev the night before he was killed. Kelly refuses to believe that her father was a bad person. Lol and Woody continue with the news that Combo is about to be released from prison and has nowhere to stay. Once it becomes clear that Combo will be staying with them, Milky refuses to let his daughter stay under the same roof as the racist man who beat him half to death. Shaun's place at college is reconsidered and he gains a place on the photography course, much to Cynthia and Sandhu's excitement. Woody proposes to Lol, and Combo moves in with them, meanwhile Milky prepares an attack on Combo.

Winter

While Lol and Woody plan their wedding, Milky plans revenge against Combo who is now about to start his first day working at a local community centre. Harvey catches Kelly smoking heroin in his bathroom and instructs her to leave immediately. When Gadget finds out he has a blazing row with Harvey before leaving to find Kelly.

Shaun has started his photography course at college, making use of his new camera bought by his mother and Mr. Sandhu. He and fellow photography student Juliette begin an assignment together. While out taking photographs, the pair meet a distressed Gadget as he looks for Kelly, with Shaun joining Gadget in the search. They eventually find her in an isolated spot where her father's ashes were scattered. Both offer to find her a place to stay, but she refuses their help, mocks Gadget's pity, and leaves with a friend who Shaun and Gadget don't know. Kelly is later seen living with him and others in a run-down drug den.

Combo enjoys his first day at work at a community centre. After going out for lunch, he is surprised to find Milky waiting outside, wanting to go for a cup of tea and talk about the racist attack that Combo launched on him seven years ago. As Milky drives himself and Combo through the countryside, the long drive causes Combo to become suspicious. Sitting in a cafe, Combo apologises to Milky and admits that he was jealous of Milky's happy and loving upbringing. Milky's relative, Rudy, then arrives with other family members, with Milky revealing that his family had sworn revenge for the beating Combo subjected him to. Accepting his fate, Combo says he hopes Milky will one day forgive him, before being ushered into the back of a van and driven to some disused dockside buildings. Combo is handed over to two white men, struggling and screaming for help as he is dragged away. He is not seen again.

Two months later, Woody and Lol finally get married at the local church. At the reception, Smell, who is with her boyfriend Harrison, tries to create a scene after talking to Shaun and Juliette (whom is now Shaun's girlfriend). Her angry behaviour mirrors Shaun's reaction to meeting Harrison at the disco earlier in the year. When alone in the snooker room, Lol asks Milky if he has seen or heard from Combo. He acts uneasy and evades the questions, with Lol remarking that Milky has not been himself and suspects that Milky was involved in Combo's disappearance.

Kelly leaves the den and walks to her sister's wedding reception. She attempts to leave a card and disappear before she is seen by anyone, but is spotted by Lol. The two sisters reconcile during a deep conversation and eventually Kelly agrees to stay and join in the wedding celebrations, becoming re-united with her family and friends. The episode ends with a wedding-dance party scene containing most of the major characters from the film and television series, including Meggy and Pob. The happy montage is intercut with a lone Milky standing at the bar, evidently remorseful over his part in Combo's disappearance.
