Soaked - nay, marinated - in the world of vintage Hollywood, Tell-All is a Sunset Boulevard - inflected homage to Old Hollywood and a hilarious assault on celebrity.
Hazie Coogan has for decades tended to the outsized needs of Katherine "Miss Kathie" Kenton, a larger-than-life star who has survived multiple marriages, career comebacks, cosmetic surgeries, and emotional dramas. But danger lurks with the arrival of a gentleman caller named Webster Carlton Westward III, who worms his way into Miss Kathie's heart and boudoir.
Hazie discovers that this bounder has already written his celebrity tell-all memoir, which foretells Miss Kathie's death in a forthcoming Lillian Hellman - penned musical extravaganza. As the body count mounts, Hazie must execute a plan to save Katherine Kenton for her fans - and for posterity.
