The old dogs of the Unsolved Crime and Open Case Squad are about to welcome a few new faces. But first, Detective Superintendent Sandra Pullman (Amanda Redman, Sexy Beast) and her loyal team - Gerry Standing (Dennis Waterman, The Sweeney), Brian Lane (Alun Armstrong, Garrow's Law), and Steve McAndrew (Denis Lawson, Bleak House) will solve their final cases together, bringing justice to decades-old murders that stumped London's Metropolitan Police. After Brian's reckless behavior endangers his place on theteam, brainy Danny Griffin (Nicholas Lyndhurst, Only Fools and Horses) steps in and rubs the rest of the squad the wrong way. Later, Sandra makes a choice that means a new boss for UCOS: feisty, fearless DCI Sasha Miller (Tamzin Outhwaite, EastEnders). The result is "a welcome new lease of life" (The Daily Telegraph, U.K.) for a show that has "plenty more tricks up its sleeve" (Western Daily Press, U.K.).
