Detective Matt Jackson has reached the end. His beloved wife, Polly, is the latest victim of 'NEON' - a serial killer who displays his victims in snaking neon lights - and he can't go on without her.
A hitwoman with one last job.
Unable to take his life, Jackson hires a hitwoman to finish the job. But on the night of his own murder, he makes a breakthrough in the case, and at the last minute his hitwoman, Iris, is offered an irresistible alternative: help Jackson find and kill NEON in return for the detective's entire estate.
A killer with both on his list.
What follows is a game of cat and mouse between detective, hitwoman and serial killer. And when Jackson discovers it's not a coincidence that all their paths have crossed, he begins to question who the real target has been all along.
