Harmon Rabb is promoted and his first assignment as Lt. Commander is to defend Capt. 'CAG' Boone in a court-martial. During a mission over Bosnia, one aircraft goes down due to a system malfunction. A Serbian helicopter shoots at the parachuting crew and, to protect them, the CAG shoots down the helicopter.

Locations: Bosnia; Naples, Italy; USS Seahawk/Adriatic Sea; Washington D.C.

GSgt. Crockett, instructor for snipers at the Boot Camp in Quantico, should be transferred to Bosnia. But there's a deal existing between him and his former commanding officers which says he won't be used in combat missions any longer.

Locations: Quantico, Va.; Washington D.C.

Harm is called in to probe the death of Navy pilot Lt. Marion, son of US Senator Grace Marion, while training with the Navy SEALS. As he was there only for two days, it seems that the death was due to gross negligence. With the reports given by his superior and comrades, combined with the results of how how he died, it seems that the actual incident is a cover-up. Analyzing his equipment and learning that it was a combat mission (and not a training mission as stated), the facts then point at murder. The key to all this could be General Behnke. Locations: Washington D.C.; NAS Roosevelt Roads, Puerto Rico; Carribean Sea; Colombia
