When Special Agent Clay Jennings and his K9 partner, Ranger, take to the streets of Denver to fight human trafficking, he is shocked by the inordinate number of stolen innocents who've been forced into the sex trade. With each new face, his resolve to help these children escape their personal horror grows stronger. El Clark, a social worker who dedicates her life to rescuing exploited kids from the streets, works valiantly to locate their families or find them a safe place to live while they recuperate. She understands the plight of these young victims more than anyone knows. When these two champions of enslaved children team up, they discover a web of deviant corruption that reaches into the upper echelons of US politics and society. Adding to the nightmare, a vicious serial killer focused on murdering female prostitutes threatens to pull Clay and El away from unearthing the man behind the treacherous, Colorado-based, child prostitution ring.
