Ming is holding the general of a new faction from the frozen North of Mongo captive and he must be rescued too as well as stopping the production of the purple mist. But Flash gets chucked down a large hole in the first of this serial's cliffhangers...
In some ways a bit of a retread of the original Flash Gordon serial and not quite as good, the action is not quite as dramatic with a bit too much padding out of the story. The addition of Frigia, and it's Arctic like wastes, is good for variety but overall this is a decent but not brilliant serial.
