Thor decides to reinvigorate himself by revisiting his old mortal persona after so many years, but he isn't ready for the Donald Blake that awaits him and neither is Asgard!

With the fate of the Ten Realms in the balance, Thor must find a way to battle a crazed and determined Dr. Donald Blake and when the hammer comes down, only one man will remain standing!
