It's a happy day at Avengers Mansion as Hank McCoy is reunited with his former girlfriend Vera Cantor. But joy quickly turns to horror when a Skrull (disguised as Jarvis) poisons Vera! The devious Skrull will revive her, but only if the Beast, Wanda, Vision, and Wonder Man retrieve the resurrection stone! However, the stone has been split into two halves...and sent back in time! The four avengers' first stop is 14th century London during the gruesome bubonic plague outbreak. And the second...Dachau concentration camp near the end of World War II. Earth Mightiest Heroes witness human suffering at its absolute worst. And in the end Hank McCoy will hold the power of life and death in his hands. What will the Beast do?
