The Fantastic Four face a bunch of old rivals in Yancy Street, but their old enemy Dr. Kragoff and his primates show up and capture them. During their voyage to the moon, the four turn the tables, but Dr. Kragoff gets away and the four are dumped on the moon. They barely manage to get to a source of oxygen, which is the Watcher’s laboratory. Using one of the Watcher's machines, Reed brings down Dr. Kragoff's ship. Susan gets Dr. Kragoff banished into a transnitron machine. Reed uses that machine to get back to Earth.
