When Mr Bell decides to ban Christmas, it's up to the 4 O'Clock Club gang to bring a bit of festive cheer to Elmsbury. While Josh makes it his mission to play Santa for one lucky person, Nathan comes home for the holidays with a big surprise for everybody.

It's Nathan and Mel's wedding. And with Nathan in charge of the cake, Josh in charge of the best man's speech and Zoe-Marie in charge of the presents, what could possibly go wrong?

After Elmsbury burns down after the wedding, Josh and Nero arrive at their new school. Nero decides it's time to have some fun, at Josh's expense. Dexter tries to impress his new colleagues with a first aid demonstration and nearly scares his new pupils to death.

Josh and the gang are accidentally picked for Mr Nunn's cross country team. When Mr Bell's new statue gets damaged, suspicion falls on the 4 O'Clockers.

Nero accidentally loses £60 of Josh's money which Mr Bell spends on a bench. Nero and Josh have to work together to get the money back, or get revenge.

When Dexter starts a choir, Josh thinks it is the lamest thing in the world - until Rachel joins and Josh decides it is the perfect way to get close to her. Fleur and Eleesha get roped into Mr Nunn's boys only boxing club.

Eli and Owen try to start an online viral to rival 'planking'. Josh bunks off school to go to an all-day music conference, but when he gets there he finds Miss Parkwood bunking off too.

When the 4 O'Clock Club gang fail to set up work experience placements, they are given jobs in the school. But if this lot are lousy pupils they are absolutely terrible teachers.

When Josh discovers some old radio equipment at school, he persuades Dexter to run a pupil radio station. Josh wants to make himself a star and get a date with Rachel, but he hasn't bargained for the other 4 O'Clockers getting involved.

Dexter gets the 4 O'Clock Club digging the school allotment. But boredom with broccoli turns to delight when Josh strikes gold. Nero joins Owen at Scouts and discovers that under the uniforms those guys may not be as silly as they look.

Josh is planning to take Rachel to a music festival. But when Mum insists Josh goes with Dexter instead, Josh has to try to get a spare ticket for the sold out festival from nerdy Natalie. Trouble is, Natalie has promised the ticket to Nero.

Josh wants to put a gig on at a village hall. But when Mum refuses to sign the booking form, Josh takes matters into his own hands. Mr Bell's scheme to create school prefects doesn't go as smoothly as he hoped.

When Josh auditions for a place at a performing arts school, it could mean that his days at Elmsmere and the 4 O'Clock Club are numbered. Will Mr Bell or Mrs O'Brian be chosen as the schools only headteacher?
