this is just episode 16 of Kamen rider Amazon. like literally they just put it on the big screen. that said it's not a bad episode I'm just not sure if it's even the episode I would have picked for theatres but I am also not a 1970s Toei executive so what do I know. basically you start with Amazon watching a bunch of mooks taking a guy up a hill and then losing them than that guy meet a friend of amazon and has a bettle suck her block. then they guy who is a bettle monster goes to blow shit up and ect..
