Navy Seal, Logan Alexander, is trying to put his life back together following a career-ending injury in Afghanistan, when he learns that his younger brother, Cooper, has been killed in an ambush while on patrol with his Ranger unit in Iraq. As Alexander delves into the circumstances leading to Cooper's death, he learns of the role that the secret arm of the Iranian Revolutionary Guard Corps, the Qods Force, plays in exporting terror. Alexander vows to avenge his brother's death. With the financial backing of a Kuwaiti billionaire, and a group of like-minded Special Forces operatives, Alexander conceives a plan that takes his team to the Sonora Desert, Europe, and the Middle East, where he comes face-to-face with the man responsible for Cooper's death.
