Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This is a supernatural horror comedy B-movie with a couple of snake scenes and a Green Iguana cameo. It's about tomb robbers who find the undiscovered tomb of an ancient immortal Egyptian blood-drinking demon named Nephratis. When one of them steals her artifacts and sells them in America, Nephratis tracks him down to get them back. B-movie action star Sybil Danning is listed as a main actor and is shown in the posters, but she only has one brief scene at the beginning. It's not a good sign when they try to sell a movie with a star who's not really in it.
In the first snake scene, archeology professor Dr. Howard Phillips (Cameron Mitchell) tells his his anthropology student niece about Nephratis. He says that she is immortal and drinks human blood every day and rips out men's hearts. Then on the night of every seventh moon, she performs a ritual to preserve her youth by killing a young girl and absorbing her entire life force and soul. Then we see Nephratis (Michelle Bauer) meet a woman at a bar and take her home. (She is not given a name, but she is played by Dawn Wildsmith who the credits show as "Anna Conda.") Nephratis tells her to wait in the bed for her. The woman takes off her clothes and walks over to the bed. She says "This bed's really squirming. What is it, some kind of new waterbed?" Nephratis says "Something like that." then pulls the covers off the bed and we see a pile of snakes and hear rattling sounds. Nephratis pushes the woman onto the snakes as she screams then dies. But this isn't her 7th moon ritual. We see that at the end.
In the second snake scene, Nephratis meets with Professor Phillips and tells him it's dangerous to refuse her. He holds up an amulet in defense. She says "Oh come now! That hasn't worked in ages." He says he thought it was worth a shot. She tells him "You can ward off evil with a serpent." Then she turns the amulet into a snake in his hand which he puts down saying, "I always wanted one of those." (Later we see that he has a pet Green Iguana, so maybe he's serious about wanting the snake because he keeps reptiles as pets.) We then learn that he is trying to trade one of her artifacts in his possession for her golden scarab, which he wants to use to make himself immortal. She says "I'm sorry, mon amour, I must be on my way. End of game!" then she shoots lightning out of her hand that kills him and drops him on the floor next to a large iguana cage. Another professor finds him there and tries to make him talk but it's too late.
The snakes are pythons and boa constrictors. They're not venomous so there's no way they could kill some so quickly, but they're probably just stand-ins for more deadly species.
