Mysterious "The One-Eyed Soldiers" was originally released back in 1966.
Anyway - As the story goes - A UN Medical Relief Organization chief doctor and also a former soldier dies while trying to elude some pursuers. With his last breath, he passes along a cryptic message about a hidden treasure of $15 million. Soon, the doctor's daughter, an innocent bystander, and a mysterious man are all on the trail of recovering the fortune.
Believe me, this one could've been a whole lot better than it was.
