Stevie attempts to stop Miranda spending all time in her pyjamas eating biscuits following Gary's departure to Hong Kong. Miranda eventually decides that the time is right to move on with her life and she deices to become the new Miranda, getting fit, losing weight and transforming into the type of woman mother and Tilly would be proud of. Miranda takes a shine to Gary's replacement but is surprised when Gary makes a sudden return.

Miranda begins to be concerned what her life is all about and what people would say about her at her funeral. Tilly and Penny are trying to organise a charity wine-tasting and Miranda thinks that maybe she should start doing some good by volunteering at an old people's home and an attempt at a parachute jump. Things don't go plan though.

Miranda and Gary go out on a date and decide to sleep with one another. Miranda and Penny are driven crazy by Tilly with her wedding plans. All Penny really wants is to see her own daughter walk down the isle. Tilly's fiancee Rupert makes a play for Miranda. Gary and Miranda come close to finally sharing a kiss after they go for a walk in the park but they are interrupted by Penny and Tilly. Miranda attempts to show Tilly what Rupert is really like but ends up with more than she bargained for when Charlie makes a play for her too. Gary shows up at the worse possible moment and when Tilly returns and discovers the truth about Rupert.

Miranda and Stevie find it hard to keep up with a new girl on the scene called Tamara who has a frenetic lifestyle. Stevie is jealous of Miranda's friendship with her and they end up competing with each other to prove they are better friends with the unsuspecting Tamara.

Miranda finds it hard to convince her friends that she is not having a breakdown. There then follows an incident in the park with an ice cream van, a handsome jogger, a teacher and a class of six-year-old children that is enough to send anyone crazy. Miranda and Penny end up in the police station, and they both are made to see a therapist for an assessment.

Miranda attempts to have the perfect Christmas but with having the parents she does it is not going to be an easy thing to achieve. When she cant take any more she hides away in her flat with Stevie Gary, Clive and Tilly instead. Things still don't go plan though when all the presents she ordered on the Internet fail to show up and she has a run in with some carol singers. After she falls out with her friends she finds herself having to spend Christmas with her parents after all.
