Thor and Loki have switched bodies. Odin, unaware of this, sees them battle and removes Loki (actually Thor) from the conflict. Thor tries to explain to Odin that, despite appearances, he is not Loki. Odin, impatient, refuses to listen and banishes Thor to Hades, the realm of Mephisto. Thor’s allies race to save him but he has been rendered immobile in an ice-like substance.
