Richard Keaton, a wealthy widowed scientist, hires beautiful nanny Liz Guinness for his gifted son Andrew, with ominous instructions to disturb neither.

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.—KGF Vissers
