GILLY MONTROSE, a high school senior from a working-class home in West Los Angeles, California, helps his father Duke-a philandering, ambitionless, single parent who cleans pools in the ritziest parts of Beverly Hills. One afternoon when Gilly is cleaning a pool, he befriends Aeura Kim, a goth, teen girl who is staying at the estate. That evening after he and Aeura sneak away, her stepmother's corpse is found in the Jacuzzi, setting a deadly series of events in motion.

Soon they become murder suspects on the run for their lives all over Los Angeles. As the plot thickens and their plight worsens, they are aided by three high school friends: Leticia, president of the debate club and Gilly's main crush; VJ, Gilly's home boy with skills; and Fern, a RTOBH, rich teenager of Beverly Hills. There's danger at every turn and romance for Gilly in the unlikeliest of times and places.

Will Gilly and his friends uncover the truth and expose the killers? What will Gilly discover about himself and love along the way?
