The Fantastic Four, the newly formed super heroes, each imbued with powers characteristic to their own strengths and weaknesses, are Reed Richards/Mr. Fantastic (Ioan Gruffud), whose idealistic ambition manifests itself with uncharted flexibility and stretching capabilities; Sue Storm/The Invisible Woman (Jessica Alba), a strong female in a mans world who gains the ability to disappear and project powerful force fields; Johnny Storm/The Human Torch (Chris Evans), whose hot-headedness gives him the power to encompass his own body in flames; and Ben Grimm/The Thing (Michael Chiklis), whose strength of character transforms him into a super-strong rock-man.
Together, they must come to terms with their newfound fame and save the world from the evil machinations of the diabolical Dr. Doom (Julian McMahon).
