Shandra: The Jungle Girl

Shandra's attacks come only by the light of the full moon - and they're always fatal. But this wild creature from the jungles of Brazil doesn't maim or destroy her victims - she pleasures them to death, draining their vital essence sexually. Four biologists set out to capture and study this elusive predator, but their pursuit becomes a race against time as Shandra winds up staking them instead. (official distributor synopsis)
