It's 1968. Hamilton Hancock is on the fast track to become a fighter pilot. He is slated to fly an F-100, F-105 or F-4 in Vietnam. Then, the "needs of the service" intervenes, and he is assigned to fly one of the smallest, slowest aircraft in the Air Force inventory, the O-2A. Hamilton becomes a Forward Air Controller (FAC) in Vietnam, and picks up the nickname "Hamfist." While Hamfist flies in air combat over the Ho Chi Minh Trail and battles an enemy gunner with a deadly record, on the ground he must also battle his inner fears and personal demons. Inspired by actual events. Contains strong language.
