In order to save his dying father, young stunt cyclist Johnny Blaze sells his soul to Mephistopheles and sadly parts from the pure-hearted Roxanne Simpson, the love of his life. Years later, Johnny's path crosses again with Roxanne, now a gogetting reporter, and also with Mephistopheles, who offers to release Johnny's soul if Johnny becomes the fabled, fiery Ghost Rider, a supernatural agent of vengeance and justice. Mephistopheles charges Johnny with defeating the despicable Blackheart, Mephistopheles's nemesis and son, who plans to displace his father and create a new hell even more terrible than the old one.
