Theatrical Release Information:
Invaders of the Lost Gold

Escorting a valuable gold shipment through the jungles of occupied Philippines in 1945, a group of Japanese troops are ambushed and killed by cannibals, although not before a dedicated few manage to hide the gold in a nearby cave. Several years later, a group of money-hungry businessmen hire a fearless mercenary to guide them to the lost treasure. As they draw ever closer to the gold, their number soon dwindles as they contend with cannibals, fearsome jungle animals, harsh elements, and the most dangerous foe of all: human greed. ~ Jason Buchanan, All Movie Guide
