Katherine Kelly leads the cast as schoolteacher Sally Wright, an English teacher embroiled in scandal and accused of murder. With Jamie Bamber. Sally has allegedly been having an affair with her 16-year-old pupil, Matty Taylor. When Matty is brutally stabbed with a broken cider bottle, suspicion lands on Sally and she’s convicted of murder – before evidence emerges that restores her freedom, but not her reputation; the case has all but destroyed the life she once had, a stable marriage, a nice home and a good job teaching English at a local comprehensive. The new series features a brand new story, but is based on the same conceit: is the protagonist innocent, or guilty?
