S2, E17: The team searches for an injured U.S. soldier, Private First Class Kevin Grant (Devon Gummersall), who recently returned from war. Upon his homecoming from Iraq, Grant discovered that his business went bankrupt, and he's about to lose the home he shares with his fiancée, Sara (Kelly Karbacz). Asked by the U.S. Army to assist in finding the missing soldier, the investigators learn from Sara that he'd been frantically trying to salvage their dire financial circumstances before returning to Iraq. Later, the team uncovers an apparent cover-up involving a firefight in which Grant was wounded. Jack and Danny travel to Iraq to learn whether or not the dangerous and controversial circumstances of Grant's last firefight could have put the soldier in jeopardy at home or if he has succumbed to post-traumatic stress and his desperate financial woes.
