A team of Americans explores a mountain in the Philippines to search for a treasure rumored to have been buried by Gen. Tomoyuki Yamashita in the closing months of World War II.
Digging continues at Breach-6, but when the team unearths a possible water trap, excavation is put on hold. To find another way into the mountain, the team conducts a LiDAR scan that reveals a cave, perhaps used by Japanese soldiers during the war.
