New Street Law follows the exploits and cases of two rival barristers' chambers in the heart of Manchester. Jack Roper is a young barrister from a working-class background, who turned down a lucrative job offer from his mentor, Laurence Scammel, QC, Head of Manchester's leading prosecution chambers, in favour of his own defence-only chambers. He has founded his own firm with old friend Al Ware, lovable chancer Charlie Darling, the no-nonsense Annie Quick and cocky Joe Stevens.
Jack's confidence grows with every case he wins and he rapidly threatens Laurence's firmly established position in the legal community – something that Laurence's ruthlessly ambitious wife, Honor, is determined to prevent. Lurking in the wings is Laurence's daughter, Laura, who works for the family chambers. She shares Jack's instinctive passion for justice, but she also poses a threat.
