The Fantastic Four are unable to pay their bills, so they are kicked out of the Baxter Building. Reading a newspaper report which says that they are needed for a "Fantastic Four Movie", the foursome decide it's the best way to get money. Hitchiking to Hollywood, the four are shocked to find out that the "director" of the movie is none other than Namor. However, Namor claims that his offer of $1 million is real, as his ancestors have seen where various treasures are buried under the sea.
The next day, Namor has the various members shooting for their scenes, but unknown to them, he is planning to defeat them. He sends Mr. Fantastic to an island with a giant Cyclops, tricks the Torch into fighting a tribe of natives who have a potion which makes them immune to fire, fights the Thing on a beach and tries to woo Invisible Girl. However, Mr. Fantastic defeats the Cyclops, the Torch destroys the natives' potion, and the Thing recovers from Namor defeating him, so they can stop him. Namor then leaves, and tells them to make the movie anyway. They do so, and make enough money to return to the Baxter Building.
