The three Craig sisters – Penny, Kay, and Joan – go to New York to stop their divorced father from marrying gold digger Donna Lyons and re-unite him with their mother.

Three sisters who believe life is going to be easy, now that their parents are back together, until one sister falls in love with another's fiancé, and the youngest sister plays matchmaker.

Deanna Durbin is all grown up in Hers to Hold, the unofficial sequel to her "Three Smart Girls" films of the 1930s. Durbin plays Penelope Craig, the starry-eyed daughter of wealthy Judson and Dorothy Craig (Charles Winninger, Nella Walker). Developing a crush on much-older playboy Bill Morley (Joseph Cotton), Penelope stops at nothing to land the elusive Morley as her husband. Highlights include Durbin's renditions of "Begin the Beguine" and the "Seguidilla" from Carmen, and a captivating sequence that includes highlights from Durbin's earlier films, presented as home movies!
