Down by the Water : Hamptons real estate agent Hope Collins-Calder can't manage her own life, much less those of her three children - four if you count husband No. 2. So, like many other upwardly mobile women, she enlists the services of a nanny. The latest entry in the daycare brigade is misfortune-prone Annabel Quick, late of Cornwall, England. A single and attractive 45, she gladly accepts the offer only to find herself in the midst of a live-action soap opera. Unhappily remarried to a Brit, Hope yearns for the first husband who abandoned her while the children run amuck. Meanwhile, Annabel is attracting men like flies. Since she's never been lucky in love, it doesn't surprise her that she falls for the least suitable candidate. Both Hope and Annabel, so dissimilar on the surface, learn that matters of the heart override logic.
