The Unit is assigned to slip into Iran to plant radiation "sniffers," but when things go awry, Mack must decide whether to leave behind an Iranian woman who served as their loyal guide to be tortured, or mercy kill her himself.

Meanwhile, back at home a wounded Jeremy has Molly at his bedside while his strangely absent girlfriend Crystal is steaming things up with one of the married men of the Unit. Her own affair long over, and fulfilling hours of community service at a free legal clinic, Tiffy clashes with lawyer Wilson James over a case of a soldier gone AWOL.
