Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This Phillipine movie is a sequel to Devil Woman (Evil Snake Girl) (1970), but it is sometimes also called Devil Woman, though the two movies are completely different. The snake-woman Manda from Devil Woman returns. She's still seeking revenge on all the people who killed her family after they discovered that she had snakes for hair, but this time Rosemarie Gil, the actress who plays Manda, must have insisted in her contract that she be allowed to show off her nice hair instead of wearing a headscarf all the time like she did in the first movie. So they came up with a device that lets us see her real hair - when she puts a magic black stone in her mouth, the Medusa-like snakes disappear from her head and she looks like a normal woman. When she takes the stone out, the snakes come back and she can continue to use them to kill all the drunken guys who try to sexually assault her.
Manda fell into some fire at the end of the first movie, but we see here that she was rescued by an evil snake queen, who I suppose is named Bruka. That name is never used in the movie, but it's in the title so I'm using it. Bruka is Manda's ancestor. She's an old woman with a giant head of frizzy gray hair and a long snake body. She's also a sorceress. Every full moon she kidnaps virgins, ties them up, and sacrifices them to poisonous snakes. She sends out her gang of henchmen - made up of savage little people, flying batmen, a wolf man, monsters made of rocks, and killer trees that can walk - to fight a young Kung Fu fighting master who can turn his magic rope belt into a super weapon and fly through the air, beating up everyone who comes at him. Just like the Kung Fu master in the first movie. None of this makes much sense, but who watches a movie like this expecting it to make sense, especially when it has almost everything you could ever ask for in a movie? (Did I mention the bat man!) The subtitles might actually add to the confusion. They're often hilarious in the version you can watch on YouTube.
I think most the snakes we see are real. There were fake stuffed snakes in the first movie, and there may be some of those in the background piles of snakes seen in this one. It's hard to tell, the picture quality of the version I watched is so bad. Most of the snakes are large pythons, but there are some other smaller snakes I can't identifys. We also see some cobras briefly.
