An alcoholic guy from our own time gets sucked into his own (bad) novel after he hits his head when he’s shitfaced. He is stuck there with his ex and her new boyfriend who he wrote into the book as a way of coping, but now he can’t escape them. 
He quickly realizes that the only way out is through, so he tries to make as little changes to the plot as possible. Unfortunately for him, the drunker he gets and the more he sees of the femme fatale, marilyn (and the handsome thomas), the less he is able to do that. More and more deaths start happening, none of which he wrote in his original novel. So can he really escape? Or will he die by his own creation?
Even though the genre is detective novel slash whodunit, we’re seeing the story from Mike’s perspective, who is first of all getting drunker by the second and secondly is from our own time. Expect a lot of cursing.
