Margaret Lockwood, one of British film's greatest stars, takes the role of a no-nonsense female barrister in this compelling courtroom drama series from the makers of Yorkshire Television's similarly themed The Main Chance. Introducing charming, ambitious young barrister James Eliot – played by Anthony Valentine – this third and final series also includes guest appearances by Anton Rodgers, Barbara Shelley and future Gentle Touch lead Jill Gascoine, among others.

Harriet Peterson is intuitive, tenacious and highly principled – qualities that have helped her succeed spectacularly in a world still largely dominated by men. But while Harriet's commitment to her profession remains undiminished through a range of typically challenging cases, her personal life grows ever more complicated... and this time, it seems there's no going back.
