Henry Bloomburg is a private investigator created by struggling writer Martin Tripp. With Martin pulling the strings, Henry has solved many bizarre cases, but one remains open: The Fly Guy - a strange man who slips unseen through the streets in an endless pursuit of the dead. 

Once Henry is on the trail of The Fly Guy, Martin discovers he no longer has the power to turn Henry’s path. Even as Martin establishes a predictable rhythm in his real life, his obsession with Henry discovering The Fly Guy’s identity in his created world threatens to dismantle everything he is.
