The Warslayer

A former gymnast lands an acting job as a warrior heroine in a series that's a great success. With that comes multitudes of adoring fans who dress up to do homage to the series. Three of the costumed fans turn out to be the real deal and whisk her away to another world full of real monsters, magic and deadly danger. She is fully expected to deal with all that as her alter-ego on the series - Vixen The Slayer - and she doesn't have any type of script to tell her what to do.
