The Hazards are an upper-middle-class family, and when only son Jonathon proposes to the working-class librarian, Stella, his mother, Joyce, seems adamant he’d be happier with Cordelia, the more suitable girl next door. Stella’s always believed Joyce doesn’t like her, but when her future mother in law “accidentally” gives nut allergy-sufferer Stella a piece of nut-filled cake, she wonders with alarm just now far Joyce is prepared to go to get rid of her, and soon finds herself fighting for her life against ‘accident’ after ‘accident’ involving Joyce. On the other hand, Joyce has always tried to put quiet, bookish Stella at ease, but everything she does backfires. Disasters abound: a jammed timer on a spray-tanning booth, a mysterious cancellation of the final dress-fitting and a nervous bride who’s gone down a couple of dress sizes. What else could go wrong?
