After solving the "Doctor of Steel Eyes" in the first episode, the "Fantastic Four" have gradually adapted to their new identities, and the team members' lives are also enjoyable. Reed (Ioan Gruffudd) and Susan (Jessica Alba) finally walked into the church. However, when the wedding was halfway through, a sudden strong wind blew and a silver lightning flashed across the sky. Reed hurriedly called "Human Torch" (Chris Evans) to catch up to see what was going on. Unexpectedly, "Human Torch" was not his opponent at all. Reed's worry became a reality: a new enemy appeared-"Silver Surfer" (Doug Jones)! Disasters began to continue all over the world. Through investigation, Susan discovered that "Silver Surfer" was only forced by "Planet Devourer" Galactus to help him find a planet in the universe for him to devour. This time the target is exactly-Earth! The "Fantastic Four" are out again. Can they help the poor "Silver Surfer" and successfully save the earth this time?
