Emily Hunt might come from a family of cops, but she never goes looking for an adrenaline rush. She lives the quiet, well, relatively quiet, life of a teacher and thrives on making a difference in the lives of her students. But she'll have to draw on a well of strength and savvy she didn't know she had as student Rafael Cerda takes her class hostage for ransom money to save his brother's life. Undercover cop Mason Taylor has been working with Rafael to find his brother and bring the cartel thugs who hold him to justice. Can he talk Rafael down from his impulsive actions? And is there something more sinister at work here than he realizes?
