When an experimental space voyage goes awry, four people are changed forever by cosmic rays. Reed Richards, scientific genius and leader of the group gains the ability to stretch his body, and becomes Mr. Fantastic. His girlfriend, Sue Storm, gains the ability to turn invisible and create force fields, becoming the Invisible Woman. Her little brother Johnny Storm gains the ability to cover his own body with flame, and becomes the Human Torch. The pilot of the space ship, Ben Grimm, becomes super strong, and covered in orange rocks, becoming the Thing. Together they use their super powers to investigate the unknown, and to foil the evil plans of Doctor Victor Von Doom, sovereign lord of Latveria. As they deal with various threats to Earth's peace, Marvel's First Family must also deal with the pressures of fame as the world's most famous superheroes, and the realities of being a super-powered family.
