Luke

Luke isn't very well suited to a Young Offender Institution - he's a nice, sensitive boy from the Valleys. Unfortunately he found himself inadvertently becoming a bank robber's getaway driver (or as it turns out, 'getty-caught' driver).

To make matters worse Luke is sharing a cell with Jason, the bank robber in question. And to make matters even worse, it's looking increasingly unlikely that Luke will make it through the first week.

Jason

Everyone has a friend like Jason - you just don't have to share a cell with them!

Overconfident, relentlessly positive and lovably idiotic, he's always on hand with a mis-remembered phrase.

Whilst Luke is sulking and convinced he's going to die, Jason is confident they'll triumph over adversity. After all, to quote Jason, "did David not defeat Godzilla?"

Dawn

Dawn spends her time at Sunnybank View split equally between looking after the inmates' pastoral needs and avoiding Creg's constant creepy advances.

She truly cares for the inmates and wants the very best for them; though will accidentally drop in the odd insensitive remark. In fairness, it can be difficult to concentrate at work when someone keeps stealing swimwear from your locker.

Creg

Creg is the senior officer on the wing, and rules the place with an iron fist (plus some steel handcuffs, and rubber bullets).

He has a soft spot for his colleague Dawn, and knows everything about her from her favourite colour to her Facebook password. Creg wants to subtly let Dawn know he's got feelings for her, but he isn't very good at subtlety (unless you consider skywriting to be subtle).

Gemma

Luke would have probably cut all ties to Jason for getting him locked up if it wasn't for Gemma - she's Luke's girlfriend... and Jason's sister.

Gemma is sweet, pretty and entirely oblivious to the fact that her mate Roger is trying to get into her... body.

Black Elton John

Black Elton John is the prison's fixer. He can smuggle in anything you want - from cigarettes to Walnut Whips. The method he uses to smuggle them in might mean you want to wash the Walnut Whips quite thoroughly...

Marcel

Marcel is the kingpin of the Young Offender Institution. He's been locked up for four years, ever since they found a policeman's helmet in his glove box (amongst other bits of anatomy).

He's softly-spoken, completely terrifying, and strangely obsessed with Twilight. But don't take the mickey out of him for this, or he'll use your head as a toilet brush.

Daz

Daz is Marcel's chief henchman. He's six foot tall by six foot wide, with a significant stammer - although that hasn't affected his self-confidence, or his right hook.

Isaac

Isaac is the lowest of the low in the prison - he's a snitch. Thin and weedy, he's like velcro to bullies.
