A young widow from Boston travels with her three children to Maine to enjoy their summer vacation. Margaret Carey (Dorothy McGuire) is helped by the friendly Osh Popham (Burl Ives), who finds the family a rent-free house vacated by a vacationing landowner. Daughter Nancy (Hayley Mills) catches the eye of a young schoolteacher, Digby (Michael J. Pollard). The owner of the summer house shows up from Europe unexpectedly, but keeps his identity a secret when he too falls for the young Nancy. The entire family gets to croon with Burl Ives in a folksy front-porch singalong. The townsfolk make the Careys feel at home to the point that they consider making the idyllic coastal town their permanent home. This Walt Disney film is lighthearted entertainment for the entire family.
