A travelling theatre company has more to it than meets the eye. It is an imaginary world commanded by the mind of Doctor Parnassus and the audience is in for more than just a show.

During a space voyage, four scientists are altered by cosmic rays: Reed Richards gains the ability to stretch his body; Sue Storm can become invisible; Johnny Storm controls fire; and Ben Grimm is turned into a super-strong … thing. Together, these "Fantastic Four" must now thwart the evil plans of Dr. Doom and save the world from certain destruction.
