Nesbitt plays Max Raban, a washed-up reporter with a fear of daylight who’s reduced to raking through bins for tacky celebrity stories to sell to his friend, unscrupulous newspaper editor (Ian Puleston-Davies).

But everything changes when his nocturnal rummaging uncovers a frightening world of deceit and distrust.

In tonight’s opener, Raban thinks he’s on to a major story when he accidentally uncovers evidence about a ‘headless man’ that could be linked to the recent murder of an Iranian.

He soon discovers a death squad at work and is determined to expose the truth about the brutal killers, which leaves him on dangerous ground.

With his unreliable track record as a conspiracy theorist, will anyone believe him or give him the chance to prove he’s back on top of his game?
