Doctor Doom hacks into Reed’s consciousness, transferring his mind into Reed’s body! Now trapped inside Doom’s body at the Latverian Embassy, Reed must fight his way back to his family and friends before Doom transforms the Baxter Building into a weapon… one that could wipe out the Fantastic Four and half of the city. But when Reed shows up in Doom’s body, the rest of the FF have to decide who they believe, and find out just how well they know Reed Richards.
