O Raptor (1980)

The lovely Laura, on a modelling job in South Africa, is kidnapped by a gang who carry her off into the jungle from where they demand a huge ransom. Two men set off in a helicopter to rescue her, little knowing what horrors Laura is enduring in the meantime in the savage clutches of a primitive and bloodthristy world. Laura's rescuers not only have to face the cruel violence of her captors - but also the horrifying lust for blood of a primitive and cruel god.
