A mysterious fungus is devastating Russian wheat fields, and all the evidence points to the fungus being developed in the USA and sent to Russia in missiles. When Solo investigates along the California coast, he encounters the madman (Jones) who has masterminded the plot in an attempt to start World War III by capturing the scientist who developed the fungus and forcing him to work with him. With the help of the scientist's daughter (Kristen), Solo must try to stop the missiles before Russia retaliates.
