G-Wing is rehearsing for HMP Larkhall's Spring Fashion Show. It's a huge event—a chance for the women prisoners to glam up and have fun, and for the Governing Governor, Simon Stubberfield, a chance to boost the prison's image. But things go badly wrong when pregnant inmate, Carol Byatt is discovered unconscious in her blood-stained bed. The finger is pointed at negligent Senior Officer Sylvia Hollamby. But new Wing Governor, Helen Stewart comes up against closed ranks when she tries to conduct an investigation.
