Chiwetel Ejiofor, Christopher Eccleston, Stephen Rea, Rafe Spall, Kierston Wareing and Lesley Sharp star in Hugo Blick’s sophisticated and gripping conspiracy thriller which delves into the heart of human morality.

Two years ago Harvey Wratten, one of the UK’s biggest crime lords, and his nephew Jay Wratten were imprisoned. After serving only two years they received a Royal pardon – but just four hours into their freedom Harvey is murdered. The Shadow Line begins…

DI Gabriel has just returned to work after being shot on an undercover job; his partner was killed and Gabriel suffered amnesia with a bullet lodged in his head.

Gabriel starts to investigate the Wratten case with his partner DS Honey. Joseph Bede, one of Wratten’s men, is keen to find out who killed Wratten, and also wants to track down Glickman, their money man. With Wratten dead and Glickman missing, Bede is left holding the fort.

Meanwhile, Jay Wratten is a loose cannon…

Bede sends his foot soldiers on a mission to find Glickman, and also the missing driver who collected Wratten from prison, Andy Dixon.

Jay Wratten is played by Rafe Spall, DI Gabriel by Chiwetel Ejiofor, DS Honey by Kierston Wareing and Joseph Bede by Christopher Eccleston.
