After years of being beaten down and bullied as a child, game inventor Corey Farrow, the Zodiac’s Gemini, isn’t looking back. When his only option for survival is to kill Alan Lowe and take his place in the Zodiac Killer’s vicious game, he decides to play by his own rules. With nothing to lose, he sets out to find a place to hide where he can think and plan his next strategy, but when his old friend Justin Finch invites him into his world, a world where he can once again reinvent himself with the girl of his dreams, will he decide he likes his new life better, or continue his mission to end the killer’s game for good? Just when Detective Darek Blake didn’t think the Zodiac case could get any weirder, Lizzy puts out a public request to find information that will support her cult theory. Aside from bringing every nut in the city to the station and revealing a man who represents the controversial thirteenth sign of the zodiac, will it flush out the real killer, or will Darek and Bay be forced to bring the remaining members together for their next big move?
