Xun Li, a hard-working and devoted husband, makes a speech at a rally for Lanternlight – a charity supporting Chinese nationals like himself who fled persecution only to find themselves at risk from ruthless protection gangs in the UK. After the rally he finishes some work at his property rental business, calling wife Rachel as he walks to his car to head home – but he never makes it as a masked figure pepper-sprays him, bundles him into a car and speeds off.

No-nonsense Yorkshire detective Alan Banks (Stephen Tompkinson) tackles each new case with the weary professionalism of a man who has seen too much. Watch him doggedly decipher the clues in the gruesome murders on his patch.
