The Omegans is a 1968 American science fiction thriller film directed by W. Lee Wilder and starring Keith Larsen, Ingrid Pitt and Lucien Pan.

[2] In the jungle, artist Valdemar (Lucien Pan) paints his wife Linda (Ingrid Pitt) while their guide Chuck (Keith Larsen) secretly plans to steal her away.

When an expedition led by Dr. Salani (Joseph De Cordova) and Bill McAvoy (John Yench) sets out to explore a mysterious, radioactive waterfall, Chuck dismisses the locals’ warnings about its cursed waters.

Back home, Salani’s experiments reveal that the water has strange properties—potentially a “Fountain of Youth.” Meanwhile, Valdemar discovers Linda and Chuck’s plot to kill him.

In a panic, Chuck attempts to kill Valdemar, but Oki (Bruno Panzalan) fatally shoots him.
