Col. "Bo" is assigned as Task Force Commander of the Dragon One Combat Task Force, and hand picks twenty five veterans for the group. Their assignment is to combat test the A-37 in all combat roles facing all combat situations, under all combat weather conditions on the ground and in the air. But when several F-4 planes are shot down by a North Vietnamese barge battery over the Mekong River, Col. "Bo" and his wingman Zach Butler are needed to locate and take out the "gattler" before it can cause any more damage. The men have the "gattler" in their sites, but the North Vietnamese have the drop on them as well, shooting down their plane and leaving them for dead. Col. "Bo" wounded, and unable to locate Butler, manages to get his four foot by six foot dinghy into the water before he passes out. When he regains consciousness he finds himself adrift in the South China Sea, the trail of blood he's left acting as a calling card for several hungry sharks. With nothing but his service weapon he takes them on single handedly--literally.
