The students are shocked by the return of Gabriella Wark, and despite her claims that she has turned over a new leaf, she gets a frosty welcome from Kacey, whose hopes of competing in the Commonwealth Games were ended in the accident caused by the trouble-maker. Taking their friend's lead, Lisa and Shaznay mark the returnee out as an easy target. Allie feels uneasy as Vaughan and the boys prepare to visit Olga on her birthday - and with the couple so wrapped up in their own problems, they don't notice Justin and Tiffany are growing closer. Hector finds an ally in Sue - and it soon becomes clear there's a chemistry between them.

Waterloo Road Comprehensive is on the scrap heap. It can be found very near the bottom of every league table there is. Its despondent teachers have given up trying to make a difference as they struggle to cope with their own personal problems as well as their nightmare day jobs. When the current Headmaster has a nervous breakdown, Jack Rimmer is reluctantly thrown into the hot seat. He recruits optimistic, educational zealot Andrew Treneman who wants to give up his comfortable private school job to bring the benefits of his elite educational experience to Waterloo Road.
Together with feisty Guidance Head Kim Campbell the three teachers - all committed in their very different ways - set to turn round Waterloo Road, painful step by painful step. Meanwhile English teacher Tom Clarkson's life is in a mess. He's about to be married to live-in girlfriend and fellow teacher Lorna Dickey and can't face telling her he is no longer in love. But much worse, he has fallen for Lorna's closest friend - drama teacher Izzie Redpath.
Man-eating French teacher Steph Haydock is delighted Jack Rimmer has been promoted - she's always fancied him but now he's headmaster, his powerful, manly charms are impossible to resist.
