A researcher receives telepathic signals from evil Martians, now long dead, who want him to build a machine that will allow them to cross space and conquer Earth. The gold that he gets through the machine as payment is now molten and buries him.
In space, Strange sees a vision of Victoria Bentley surrounded by machinery. He lands on a jungle planet inhabited by monstrous creatures and finds an underground cavern with an elaborate machine. The equipment emits a mental challenge--Yandroth, Scientist Supreme, claims to have unlocked the 'inner-most secrets of the cosmos' and intends to make Victoria his queen to conquer and rule many planets, including Earth. Strange realises a challenge of science vs. magic awaits him.
