Harper gets caught in a firefight when she, Abe and Maya travel to Syria to investigate a Marine accused of desertion. Also, Col. Turnbull travels to Germany to be with her wounded son, Adam (Derek Klena).

When two Marines are accidentally killed in a weapons test, Abe and Harper square off against Trey as prosecution and defense for the soldier who is accused of tampering with the system. Also, Abe helps out his best friend's widow, Alex (Justine Cotsonas), and Col. Turnbull gives Maya an important assignment.

Abe and Harper's investigation into the accidental overdose of a Marine takes a turn when they can't find any fingerprints - even the deceased's - on the pill bottle, leading them to believe he was murdered. Also, Abe receives a warning about testifying in a lawsuit against the Corps, and Maya is concerned that her brother does not have his mental illness under control.
