When a soldier in Afghanistan kills his commanding officer, Judge Advocates Capt. John "Abe" Abraham and Capt. Maya Dobbins are assigned to the case as prosecution and defense lawyers by their commanding officer, Col. Glenn Turnbull.

Captains John Abraham and Maya Dobbins head to a war zone when they are assigned to opposite sides of the courtroom in the case of Marine charged with abandoning his post during combat, resulting in the deaths of three soldiers. Also, Major Trey Ferry must iron out a diplomatic spat, and Lt. Harper Li works to balance her duties to the Corps with planning her wedding.

Major Ferry and Lt. Li are assigned to find out who leaked information about a Marine who was set to become the Corps' first female Infantry Captain, which may have led to her attack. Also, Capt. Abraham is approached by his best friend's widow, Alex, who is considering suing the Corps for her husband's wrongful death and may ask him to testify.

When a dying Marine confesses his involvement in covering up the murder of an Iraqi civilian more than a decade ago, Abe and Trey are assigned to prosecute the accused killer - a sitting U.S. congressman. Also, Maya helps her brother prepare for his state senate race.

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, and Col. Turnbull gives Maya an important assignment.

Abe and Harper try to track down a website owner who is inciting violence by having Marines confront and expose civilians who are publicly pretending to serve in the Corps. Also, Abe's relationship with Alex becomes more complicated; Rami faces a crisis of conscience when he and his wife, Nazil, go for their citizenship test; and Col. Turnbull anxiously awaits word on her son's status after she approves an overseas airstrike.

Turnbull and her husband, Asa, disagree about how to handle their son Adam's physical therapy.

Abe and Harper's investigation into a Marine recruiter's alleged misconduct may be derailed when the key witness refuses to testify.

When a Marine is accused of helping a terrorist escape from Guantanamo Bay, Abe and Harper believe that they have an open-and-shut case until they are mysteriously denied access to key evidence without explanation. Also, Trey and Maya attempt to get Rami reassigned back to their office.

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.

Abe's colleagues must defend – and reluctantly prosecute – him when he is arrested and court-martialed for mutiny in regard to a 2010 mission in Afghanistan where he was one of the only survivors.
