01Theo Mackenzie (Reggie Yates)
Theo's the clever kid from Lewisham who came to Trinity to make his parents get off his case. He never expected the place to be so – what’s the word? – weird.
Still, Theo’s a happy-go-lucky sort, and not the kind of guy to let a vicious, elitist regime get him down, and after a few initial qualms he’s knuckling down to make the best of things - helped by the fact he’s hooked up with the hottest girl in the year, Rosalind. Result.

02Charlotte Arc (Antonia Bernath)
Swotty but fiery Charlotte has always wanted to go to Trinity. Her father, Richard, was once a Don there, and she always imagined she’d follow in his footsteps.
But when he dies mysteriously weeks before she’s due to attend the college, her world collapses. Charlotte’s got issues to deal with – not least the fact that she’s getting up to a lot of things her clergyman father wouldn’t approve of.

03Dorian Gaudain (Christian Cooke)
Dorian is the forty-second Earl of Colfax and eldest son of the Marquis of Ravensby, born with a full set of silver cutlery in his mouth. He's also President of Trinity’s Dandelion Club, which means he doesn’t have to do any work.
Life for Dorian is a constant whirl of sex and debauchery. But with a new Warden on the scene, and an unlikely love interest in the guise of Charlotte, it seems that all could change...

04Rosalind Gaudain (Isabella Calthorpe)
Rosalind is Dorian’s cousin – and his equal for good looks and witty insouciance. That said, she’s got a lot more going on up top: a brain!
She’s an ice queen and social goddesss, used to getting what she wants. At present, she rather wants Theo Mackenzie – the slightly rough kid from Lewisham who lives down her corridor. But that’s not going to last long, is it?

05Dr Angela Donne (Claire Skinner)
Dr Angela Donne is the new Warden of Trinity. A determined, rather lonely soul, she had a torrid time at the archaic college as a student and is now determined to make the whole college fair, modern and welcoming to women.
Unfortunately, Maltravers is determined it stay unfair, old fashioned and as beastly to women as possible. It’s going to be a hard fight.

06Dr Edmund Maltravers (Charles Dance)
Devious, acerbic, brilliant and rather sinister - Dr Edmund Maltravers has been Dean of Trinity for over 20 years. Although supposedly second in command of the college, he knows the place better than anyone else and has way in most things.
Rigidly traditional, he detests those who would change his beloved Trinity – not least because they might uncover dark secrets he would rather keep quiet.

07Maddy Talbot (Elen Rhys)
Maddy loves the poetry of Dylan Thomas and things beginning with the letter N. A kid from the valleys who’s been ploughing her own furrow for so long, she can’t remember normality.
As a result, she’s a slightly bemusing friend to Theo and Charlotte. She’s got a hopeless crush on Theo. He just doesn’t seem to notice. Poor thing.

08Angus (Mark Wood)
Angus and Raj are two profoundly average male, virgin students. Best friends, they’re almost never apart.
Pursuing nothing more than their next illegal high and the dim possibility that a girl might sleep with them, they always get entwined in the most important goings-on at Trinity.

09Raj (Arnab Chanda)
And here's the other half of Trinity's most haphazard duo - Raj. Despite their fresh looks, budding intellect and, erm, swarming pheromones, things rarely work out well for them. In fact, most of the time they end up naked, and not in a good way.
