Helen Stephens is wrongly sentenced to 12 years in prison for murdering her boss Eric Bridges, the managing director of Entirely Tiles. Although she is sure that it will only be a matter of time before this mistake is rectified, everyone around her seems to be conspiring to keep her behind bars. Lawyer Tony is incompetent, sister Laura wants her flat, and fiancé Justin - her alibi - has disappeared. Colleague Henry seems to be the only one willing to help, but he has an ulterior motive.
