In 1967, during the Vietnam War, there is a place of deadly fighting, strange sightings and rumors, and whispers of hidden treasure, it is known as the Quế Sơn Valley. As the war intensifies, a Marine patrol is ambushed, men are wounded; one vanishes without a trace. Another patrol kills a Viet Cong Tax Collector; a curious map is removed from his body. Elsewhere, Marines confront and kill an enemy squad; they discover an unsigned letter written by an American. Later, the Marines kickoff Operation Hillandale; Bravo Company will use explosives to destroy enemy caves inside Hill 270.
350 miles to the south, Ryan, a former Marine turned civilian, is working in Saigon and has fallen in love with Vân, the beautiful daughter of a powerful South Vietnamese general.
