Mr Khan's day off from being a 'busy' community leader is interrupted when Alia fails her exams, prompting Mrs Khan to lay down the law. She tells Mr Khan to sign Alia up at the Muslim Academy, but when he finds out how much it costs, Khan decides there's a better option...
Meanwhile, Shazia has invited Debbie, her best friend and boss, round for dinner with the intention of asking her to be chief bridesmaid at her wedding. But she hasn't counted on her dad inadvertently inviting an extra guest...
Mr Khan is off to meet the mosque manager, whom he expects will finally get him onto the mosque committee. Naani, Mr Khan's mother-in-law, is visiting from Pakistan. Mrs Khan is worried because she has been doing nothing except stare into space all day. She tells Mr Khan that, until Naani perks up a bit, she will be staying with them indefinitely.
Khan hurries to the mosque to try and enroll Naani onto a course activity and prove to Mrs Khan that Naani can go home, but Khan has a disagreement with the mosque manager. He storms out in a strop and puts plan B in to action, taking Naani to a not-entirely-appropriate alternative venue, where she meets a not-entirely-appropriate new friend.
Mr Khan wants to go to the mosque to meet the local MP, who is visiting to endorse the mosque's mobile men's health check unit. Khan needs to take a guinea pig, and future son-in-law Amjad fits the bill perfectly. Mrs Khan and the girls are off to buy baby clothes for a friend's new baby.
Mrs Khan loves babies, and is looking forward very much to Amjad and Shazia providing her with lots and lots of them in the very near future.
Amjad's health check does not quite go to plan as Mr Khan causes him to attend the doctor's for real, potentially creating terrible consequences for the family.
The imam at the mosque calls a special fast and Mr Khan uses it to compete with Dave, the mosque manager. He is suffering badly, and the old double whammy of low blood sugar and a dodgy bladder means he is a ticking time-bomb.
Alia has a foreign exchange student staying, and Shazia has announced she has been offered a great job opportunity in India, which will mean more money and the chance to put down a deposit on a new flat. However, being away for twelve months will put her engagement to Amjad in jeopardy. Mrs Khan decides the only way to save their relationship is to pay the flat deposit for them, and she sends Mr Khan to the building society to secure the all-important loan.
Khan arrives for his meeting with the building society manager starving hungry and gasping with thirst, not perhaps the perfect conditions to persuade him to give him a loan.
Shazia and Amjad are going up in the world; they have managed to get a trial day at an exclusive gym. Mrs Khan is keen to go along to the bums and tums class, but Mr Khan is less impressed. He is more interested in contacting a famous Pakistani cricketer to operate this years's Eid tombola at the mosque. He uses his newfound hobby - the internet- to try and track him down. Mr Khan thinks he has found a cricketer, and arranges to meet him at the mosque, but the person who shows up is not who he expects, creating a potentially embarrassing situation for the mosque and the Khans. Mr Khan has to race to find Mrs Khan at the gym before she finds out exactly what has happened. Things go from bad to worse as Khan is forced to hide and gets mistaken for a yoga guru
Mrs Khan is having a makeover but her husband is not impressed - new dresses cost money. He only has eyes for the promotional video Dave, the mosque manager, is making to promote the mosque in the local community. Mr Khan thinks he is the perfect person to star in the video. He is, after all, a fine example of Pakistani manhood.
Dave, however, has other ideas, and wanting to promote a more modern image of mosque-goers, he chooses Sajid, an attractive, 'metrosexual' friend of the Khan family.
Khan decides if you can't beat 'em, join 'em and goes to extreme lengths in order to prove to Dave that he's modern and metrosexual too. What he hasn't realised is that Sajid is home alone with Mrs Khan, and the reason for her makeover suddenly becomes blindingly clear. He rushes home to confront the pair, but is not prepared for what he discovers when he arrives.
It's Christmas Eve and Mrs Khan has decided to have a traditional family Christmas, their first one ever. Mr Khan is very 'bah-humbug' about the whole thing; he thinks Christmas is just an excuse for people to get ripped off and he believes the Khans have the perfect reason not to celebrate it - they're Muslim!
Mr Khan is collecting the family's 'unwanted' items for the Mosque charity collection, and the biggest donor will be named Muslim of the Month. Nevertheless Mrs Khan sends him off to buy a tree and some decorations while she and the rest of the family set about trying to prepare to stuff their first Christmas turkey!
Things take a turn for the worse when he realises he has accidentally dumped Mrs Khan's favourite family heirloom in the charity collection. Can he get it back, bag the very last Christmas tree in Sparkhill and get back home in time to make this a Khan Christmas to remember?
