Wealthy widower Richard Keaton engages young widow Elizabeth 'Liz' Guinness as the 4th consecutive nanny for his pre-teen, equally science-devoted son Andrew, with instructions to disturb neither. She learns of mother Alycia's fatal fall, an official suicide but was probably murder. Dad keeps Andy at a distance, so he draws towards Liz. Real danger starts when Richard's brother, novelist Blain, arrives with his friend Jillian, to sell the ancestral estate against Richard's will.
Unfortunately the movie At the Midnight Hour is not yet available on HBO Max.
