Three members of the Fantastic Four - Mr. Fantastic, the Human Torch, and the Thing - have been lured into the deadly Negative Zone by the evil Blastaar. The Invisible Woman must enlist the aid of the Silver Surfer to help her find and rescue her teammates - but it isn't Blastaar they need to be rescued from! Blastaar has brought the Fantastic Four to his home to ask for their help against a threat to the Negative Zone: Prodigion, a destroyer of worlds akin to Galactus, the planet devourer to whom the Silver Surfer was once Herald. Seeing a chance to atone for his past actions in Galactus's service, the Surfer joins the Fantastic Four in their attempt to stop Prodigion - but is Prodigion really a Negative Zone version of Galactus, or is the truth far more deadly than even the world's greatest heroes can imagine?
