Oscar winner Helen Mirren is Detective Jane Tennison, perhaps the greatest role and performance of a female police detective, ever (San Francisco Chronicle), in a series that won more than 20 major international awards and raised the bar for police drama.
In the final series, Detective Superintendent Tennison is pushing 60 and facing the death of her father. Alcohol, loneliness, and the job have taken their toll, but she is determined to end her exemplary career by solving one more case: the brutal murder of schoolgirl Sallie Sturdy. Weeks away from retirement and struggling to stay afloat, Tennison forms an emotional bond with Sallie's closest friend, Penny Philips, and unwittingly puts the teenager's life in danger.
Guest stars include Frank Finlay (The Pianist), Stephen Tompkinson (Wild at Heart, Brassed Off), Gary Lewis (Billly Elliot), and Eve Best (Nurse Jackie).
