You've got to fight for everything when you start with nothing.

Susan Knight has a good life. So she turns a blind eye to the gambling winnings her husband Donny puts through the books at her salon. After all, he needs some way to unwind. At work, he is headteacher at Second Chance, an alternative provision school for kids who have nowhere else to go.

Being the headteacher gives Donny respect, money, and charm. But respect can be lost, money can be stolen and charm can only go so far.

The kids at the school all have a story to tell - as do the staff. Drugs, debt, violence and threat are part of their everyday lives. Donny's got this far by never playing by the rules. But to keep winning, you have to keep chancing it all. To stay at the top means risking everything.

Susan knows Donny walks a fine line - but if he stumbles too far on the wrong side of the tracks can she stand by him? And for Donny, if he loses Susan, he knows he might be pulled back into the life that's been waiting for him all this time...
