Ian Bonar is Stevie, a wannabe musician whose look is a hybrid of Jarvis Cocker and early Elvis Costello. Working with his drummer pal Neil (Matthew Baynton) in a call centre, they dream of breaking into the indie music scene. To do this they require additional band members. Step forward the driven (and drinking) guitarist Billy (Kieran Bew) and slightly scatty bassist Emily (Lyndsey Marshal), who has a sideline in making sculpture from hair.

Chancer John lives for playing the odds - and he's always willing to take a calculated risk.

Lured by her huge payoffs, John finds himself sucked into a surreal and dangerous word ruled by money, power and control. The question is how far will John go for the ultimate last big win?
