Following the death of Carmen Flores, the lubricious Mexican star, Adela Cork buys her Hollywood house. Hoping to escape from the domineering Adela, her brother-in-law Smedley, who has lived with her since losing his money, searches the house for Carmen''s legendary lost diary, in the belief that its scorching revelations about the sex life of her fellow stars will make him millions. He is helped and hindered by a safe-blowing butler, a pompous movie mogul, a posse of unemployed scriptwriters, and the redoubtable Adela herself. Fortunately, Adela''s sister, ''Bill'' Shannon, not for nothing nicknamed ''the Old Reliable'', is on hand to ensure a satisfactory outcome. A light comedy which is also a sharp satire on Hollywood mores.
