Four courageous college graduates become heroes when they successfully complete a 15-hour coast-to-coast plane flight. Alas, things don't go so well for the foursome when they return to earth to seek out employment. Chris Thring (Charles Farrell) has a particularly rough time of it, but his sweetheart Catherine Furness (Janet Gaynor) remains faithful through thick and thin. Trouble brews in the form of Chris and Catherine's mutual friends Mack McGowan (James Dunn) and Madge Rountree (Ginger Rogers): Catherine thinks Chris is in love with Madge, while Mack falls in love with Chris? and on and on it goes. Shirley Temple shows up in the early scenes as a plane passenger, while that grand old trouper Gustav von Seyfertitz sheds his usual villainous image as the film's avuncular last-minute problem-solver. Change of Heart is based on a novel by Kathleen Norris.
