After a plane crash in which Indiana Jones and the beautiful Francisca are the only survivors, the two adventurers are captured by a menacing group of Incan natives -- who lead the pair straight to Francisca's brother, who holds the key to the priceless Chimu Taya Arms of Gold. Unfortunately, he also holds a big grudge against Indy, and our intrepid archaeologist now finds himself being offered to ancient Incan gods as an all-too-human sacrifice!
