In the wake of a disastrous firefight with a Mexican cartel, two El Paso police officers find themselves in a military hospital facing a debriefing about what went wrong. As their accounts unfold, Tony, a by-the-book cop, begins to believe that hotheaded Matt might have divided loyalties. Could he have intentionally led the team into a trap that saw the death of a beloved senior officer? Or is the truth even more terrifying than Tony dares to imagine?
