Hazama travels to South Vietnam after Yabu went missing there. A month earlier, Yabu moved to Saigon to restart his medical career, but two weeks after his arrival, the hospital he worked at was bombed by terrorists. Hazama meets with photojournalist Takayanagi, the man who referred Yabu to the hospital, who tells him that Yabu's last known whereabouts is a village called Da Lat. Takayanagi invites Hazama to join him in the American military convoy heading to Da Lat. They board an armored personnel carrier with the convoy's commander, U.S. Army officer Bob, as well as the Vietnamese guide and interpreter Phan. On the way, they are ambushed by the Viet Cong and in the midst of firefight, Hazama attends to Steve, a wounded soldier. However, they are all captured by the Viet Cong.
