At the Midnight Hour (1995)

"At the Midnight Hour" is a 1995 Drama movie directed by Charles Jarrott and starring by Patsy Kensit, Keegan MacIntosh. 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.
