Down on his luck private eye Holland March and world weary muscle-for-hire Jackson Healy have nothing in common until they're plunged into a life-or-death mystery when the missing persons case they're both following makes them the target of trained killers. Now grudgingly working together along with March's precocious teenage daughter Holly, they must navigate the smog-filled days and neon-soaked nights of 1970s Los Angeles to follow a labyrinthine trail of clues to finally find Amelia, the missing girl. But this is only the tip of the iceberg, as Amelia leads them to a multi-billion dollar conspiracy involving a murdered porn star, Amelia's powerful mother and people at the highest levels of the Detroit auto industry who will do anything to protect their secrets. Healy and March must now call upon all of their resources - legal or otherwise - to save themselves and ensure that the truth comes to light.
