Major Thomas Egan is an officer with the U.S. Air Force stationed at an Air Force Base near Las Vegas, Nevada. He is a former F-16 Falcon pilot, married, with two children who live with him in a suburban house off-base. His current assignment involves flying armed MQ-9 Reaper drones in foreign air space in support of the U.S. War on Terror. He is admired by his commanding officer and support staff for his calm demeanor, precise flying, and adaptability. Privately, he is concerned about the assignment, which he took after being informed there was reduced call for and increased competition among fighter pilots in the Air Force. His previous CO informed him that a tour flying unmanned aerial vehicles would look good on his record and would increase his chances of being posted back to a flying assignment. At first, the new assignment seems stressful but relatively benign. He is assigned to attack more clear-cut terrorist cells, vehicles, and facilities in Afghanistan. He flies these assignments during daylight hours over his targets, which is night-time in Las Vegas, leaving his days free for his sleep period, and to spend time with his wife and children. However, the high-tempo assignment – he is attacking targets on almost a daily basis – begins taking its toll. His wife notices the stress he's under and he begins drinking when off-duty. Still, his performance is excellent and his crew is rated among the highest in the squadron, so, on the orders of his commanding officer, he is assigned to more challenging missions under the direction of CIA controllers. Many of these targets are in Yemen and Somalia, places where the U.S. has no acknowledged military mission. The targets themselves are increasingly morally ambiguous: crowds the CIA controller calls terrorist cells, public buildings the controller says are sleeping spots for high level terrorist leaders or factories for making explosives. Collateral damage goes from being a rare occurrence to a routine one. On several occasions, the CIA controller orders strikes on obvious civilian targets – including women and children – describing these casualties as unfortunate but necessitated by terrorist leaders using them as human shields. Egan's performance declines and his drinking intensifies. He narrowly avoids being arrested for drunk driving, and starts avoiding home commitments, not wanting to inflict the stress he's under on his wife. He relishes a rare overwatch assignment protecting U.S. troops as they sleep, but must break a promise to his wife in order to perform the mission. On another overwatch mission, the troops are killed by an improvised explosive device that Egan could not protect them from. After a stress-induced violent episode at home, Egan's wife demands to know the details of Egan's work, and Egan tells her. She appears appalled. Soon after, she says she is leaving him and taking the children to Reno, Nevada, blaming his drinking and violent behavior. Finally, Egan cracks. His CIA controller orders a strike on a small group of civilians responding to an explosion at a building Egan had previously destroyed. Rather than obey the order, Egan simulates a glitch in the UAV control system and the targets escape. His CO has no choice but to demote him away from the attack role into a surveillance one. While on a surveillance mission, Egan notices a man whom he had previously watched rape a woman several times approaching her home. His Mission Intelligence Coordinator had previously described this man as "a bad guy. But not our bad guy." Egan conspires to send his support staff on a break, then uses the surveillance UAV to attack and kill the rapist. He then leaves the base without orders and is seen driving away from Las Vegas toward Reno.
