A quiet afternoon at the Baxter Building is interrupted by a surprise attack against Ben Grimm…by the Human Torch! Oh my, why has Johnny Storm ambushed his long-time friend?

Using his trademark exact calculations, the Mad Thinker sends his replica androids to capture the Fantastic Four! And with textbook precision the thinker's sinister plan rolls towards completion! However, the FF's familiar foe may have once again miscalculated the human element! Giving Mister Fantastic an opportunity to outthink the thinker!
