The gang are back at College after the summer break. Their hedonism knows no bounds as they live life to the ethos of no consequences, no tomorrow and you can all live forever. Their care-free bubble abruptly bursts when a near-stranger dies so needlessly, sending a shockwave through the group. The tragedy leaves Thomas questioning everything - his faith, his family and even his choice of friends. Effy returns, but no longer with her queen-bee status. Her best friend, Pandora, is as adorable and kooky as ever. Twins Katie and Emily are visibly different - after leaving her sister's shadow Emily is head over heels in love, but while she's finding out what life is really like, Katie is left behind in a family meltdown. Naomi seems to have more to hide this series; while JJ finally realises what love is. Meanwhile Cook is trying to simultaneously exorcise his demons and not reveal his weaknesses, and Freddie finds out that love can lead you to the edge.
