Bernice and Fontayne grew so close people said they could go for sisters, but time sent them down different paths. Twenty years later, those paths cross: Fontayne is a recovering addict fresh out of jail, and Bernice is her new parole officer. When Bernices son Rodney goes missing on the Mexican border, his shady associates all in hiding or brutally murdered, Bernice realizes she needs someone with the connections to navigate Rodneys world without involving the police…and turns to her old friend. The pair enlist the services of disgraced ex-LAPD detective Freddy Suárez and plunge into the dim underbelly of Tijuana, forced to unravel a complex web of human traffickers, smugglers, and corrupt cops before Rodney meets the same fate as his partners.
