Ming the Merciless, ruthless ruler of the planet Mongo returns with a death ray that he aims at the Earth. Flash Gordon, Dale Arden and Dr Zarkov must again head for Mars where Ming has built a base and do battle with Queen Azura who turns people to clay.

The extra three chapters do little to help this tedious follow up to Flash Gordon (1936). There are still plenty of low-tech effects (those spaceships are still wonderful!) and the Clay People are memorable monsters, but overall it's a drag and not a patch on the first film.
