The Kill Team profiles four young American men, who referred to themselves as the "Kill Team," that carried out a string of war crimes in 2010, during the United States' invasion of Afghanistan, systematically murdering Afghan citizens. The film focuses on Private Adam Winfield who attempted, with the help of his father, to alert the military to the murders his platoon was committing. His pleas went unheeded. Faced with threats to his life from superior officers and other members of the military, Winfield makes a split-second decision that changes his life forever. The Kill Team follows Winfield and his family through the wartime events and legal proceedings that follow, interspersed with interviews of the other soldiers involved, and video footage from Afghanistan, revealing first-hand revelations of a war culture rooted in hatred, social pressure, and sociopathy.
