A new term at Waterloo Road gets off to a noisy start when Karen arrives to discover the alarm going off and her new site manager, Rob Scotcher, taking a laid-back approach to the problem.

When a Year 12 pupil abandons and then claims her baby, Karen is concerned for the girl, her child and the dark secret she's keeping.

New teachers Eleanor Chaudry and Daniel Chalk want to make a good impression, but the kids aren't going to give them an easy ride.

"Chalky" is instantly marked out as a soft target, while Ms Chaudry's strict rules land Sambuca Kelly in the "cooler".

And when Richard Whitman, the Director of Education, arrives unannounced, he makes no secret of his disapproval of both the PR launch and Karen's professionalism.

At the memorial service Denzil struggles with his grief, especially when new girl Scout inadvertently steals Sam's jumper, while Jess makes her own shock admission.

But when the lead inspector discovers that Chris has allowed a pupil to spend the night at his house, it is Karen's job that's on the line.

As the staff do their best to rally round, Jess issues Eleanor with an ultimatum: if she really wants to save Waterloo Road, she needs to take action.

Left scarred by a pupil's knife attack at his last school, the new head is called to court to hear the verdict of the trial.

Elsewhere, Phoenix and Harley Taylor struggle to hide the death of their nan and Finn begins to show an interest in newcomer Trudi, sister of the nearby estate's ringleader Tariq Siddiqui.

Elsewhere, Emily tries desperately to prevent Scout from moving away with her foster parents and Ronan and Vicki say goodbye to Waterloo Road.

DSC member Mason Price threatens Tariq's fresh start as the gang targets Finn, and Grantly criticises the work of dinner lady Maggie Croft, but also learns how to make easy money.

Candidate, Nikki's disciplinarian approach gets results, but Tom takes offence when she offers him some words of advice about Josh.

Fleeing Waterloo Road, he takes Fleur away from her nursing home to a cottage near where they honeymooned, in the hope it will jog her memory.

Meanwhile, Jez realises he needs to prioritise his relationship with his children, and Kyle oversteps the line when he is caught selling illegal vodka shots, punching Nikki in the face and being permanently excluded.

The final day dawns on Waterloo Road in Rochdale as Michael arrives to break the news of the school's imminent closure.

Reeling from the realisation, Michael tackles the possibility of taking a handful of students with them and asks Lorraine to consider setting up a boarding house at the new school.

His worries soon escalate when Eugene and the MSB invade the school to teach Finn a lesson, while Tariq receives a crossbow in the post to which he discovers Kyle has ordered as part of his own revenge against plot.

As Tariq realises the error of his ways, he warns the prom goers of the crossbow just as Kyle takes aim – and Josh arrives to save Finn.
