The flat across the hall is up for rent and Basil is keen to impress his new neighbour the foxy Miss Ella. But chaos ensues, as the landlord tries to keep trouble at bay and Basil out of the way while he tries to let the flat.
It appears that everyone has forgotten Stephen's birthday, so he throws his own, only trouble is that Basil and Molly Have also organised 2 separate surprise parties for him without telling anyone.
Ella and Molly try to convince Basil and Stephen to stop eating junk food and get fit at "Healthy Harry's Healthy World Gymnasium". Once there Harry tricks them into signing a contract to be on his embarrassing TV fitness show. Can Basil and Stephen get out of it?
Molly experiences the ups and downs of being in love for the first time. But will Molly's choice in boys meet with the overly protective Uncle Stephen's approval?
Basil is writing a family chronicle when he receives a parcel from Ella. She claims the box is alive but inside was Basil's nephew Bingo. who causes trouble for the gang such as: eats Ella's dress, eats Molly's French homework, throws up on Dave's schoolbag, uses the toilet and eats the rabbit out of Stephen's top hat and finally, he wrecks Anil's cafè for £2.42.
Stephen gets a role in a TV soap that catapults him straight to stardom, and TV interviews, guest appearances and even a magazine spread all follow. But fame proves something of a rollercoaster ride for Stephen.
Anil becomes depressed because his cafè isn't doing well because a new rival restaurant had opened down the road. Trying to help, Basil takes Anil to a cookery lesson taught by Ainsley Harriott but the lesson does not have any effect on Anil's cooking and the owner of the new restaurant, Orso, buys the café for £50 and the health inspector closes the cafe down so Anil has his cafè back.
It is the quiz night at the cafe. Basil and Stephen are going to need more than their brain cells if they hope to beat Molly and Ella to the prize. An epic battle of the sexes ensues as the Girls take on the boys. Will Basil and Stephen keep the crown?
It is Christmas and Basil wants a perfect Christmas show with all the trimmings, but things do not go to plan when Stephen's Aunt, Cousin Mortimer and Bingo turn up and not one of the people who Basil told Dave to invite.
