There’s chaos in Hollywood at the end of the New Year’s Eve countdown. Working her graveyard shift, LAPD detective Renée Ballard waits out the traditional rain of lead as hundreds of revelers shoot their guns into the air. Only minutes after midnight, Ballard is called to a scene where a hardworking auto shop owner has been fatally hit by a bullet in the middle of a crowded street party. Ballard quickly concludes that the deadly bullet could not have fallen from the sky and that it is linked to another unsolved murder --- a case at one time worked by Detective Harry Bosch. At the same time, Ballard hunts a fiendish pair of serial rapists, the Midnight Men, who have been terrorizing women and leaving no trace.
