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 jungle adventure/exploitation movie that shows, as the title promises, a woman tied up and sacrificed by superstitions savages. There are several scenes with snakes in the movie.
white man hunting animals for zoos and circuses named Samson goes to a house where his friend and daughter live and they invite him to wash up before lunch. When he pours some water into a bowl, a frog falls out of the pitcher, then a parrot jumps into the water bowl for a bath. When he reaches into a basket for a towel, he finds a Boa Constrictor. Instead of fearing the snake or killing it, he just picks it up and sets it on the edge of the table, saying "That's no way to treat a guest." I liked this guy immediately. Anyone else would have stomped it to death with his boots.
Samson is forced to defend himself from an attacking leopard by wrestling it then stabbing it to death. Some Vicuni Indians witness the killing. They worship leopards (which they call tigers for some reason) so in return they kill Samson's friend and kidnap his friend's daughter to kill her later in a virgin sacrifice that is supposed to appease the Tiger God.
Samson chases the Indians to try to save the girl. During the jungle chase, we see a snake on a branch overhead as the kidnappers pass by. Later, we see two Vicunis pull some snakes out of a basket (that somehow appeared out of nowhere) then dump the snakes into a pit and cover the pit with branches to hide it. When Samson comes upon the pit, he's not fooled. He looks under the branches and sees the snakes. One of the Vicuni comes up behind him and tries to push him into the snake pit, but he turns around just in time and tosses the Indian into the pit where we are left to assume that he suffered a horrible death from the snakes (which are actually a few harmless boa constrictors and a black snake with partial yellow bands that I wasn't able to identify yet. It's probably a snake from Guatemala, where the movie was filmed.
