Plot

In the suburban Hummingbird Hill, lawyer Harry King and his wife Tacey have trouble retaining a nanny for their three young, rambunctious boys: Larry and Tony, both of whom get into frequent mischief with the family dog Henry; and baby Roddy. When the latest in a string of servants (all women) quits, Tacey advertises for a replacement and hires Lynn Belvedere sight unseen. However, she discovers that Lynn Belvedere is actually a man upon his arrival, a mysterious one with many skills and achievements – and who declares himself to detest children. Nonetheless, the Kings reluctantly agree to a trial period during which Belvedere quickly wins over the boys. However, his mysterious nature intrigues both of their parents, and Harry becomes annoyed by his condescending attitude.
