The film starts on Earth. A deadly plague has been ravaging the planet, known as the Purple Death because it leaves a purple spot on the forehead of its victims. Ming the Merciless is suspected to be behind the plague, and Flash Gordon is sent with Dr. Alexis Zarkov and Dale Arden to the planet Mongo to find the cause of the plague, as well as a cure.

Amid the political chaos sweeping across the world in 1939, a new terror arises — the Purple Death — and people around the world succumb at random by the hundreds, then thousands, with the identifying symptom being a purple spot on the victim. The authorities are baffled as to the cause or the treatment, and panic is spreading. Dr. Alexis Zarkov (Frank Shannon) determines that the Purple Death is linked to extraterrestrial events. Along with Flash Gordon (Larry \”Buster\” Crabbe) and Dale Arden (Carolyn Hughes), Zarkov finds an alien spaceship, which they recognize as being from the planet Mongo, home of their old enemy, Ming the Merciless, spreading some sort of dust in the Earth’s upper atmosphere. Flash, Dale, and Zarkov head for Mongo, where they discover that Emperor Ming (Charles B. Middleton), whom they believed had been killed at the end of their battle with him on Mars (told in Flash Gordon’s Trip to Mars), is still alive. He is threatening not only to conquer all of Mongo, but is attacking Earth again, using a “Death Dust” spread by his spaceships that will eventually destroy everyone on Earth.
