Peck plays Phil Green, a charming and friendly widower with a grandson, Tommy (Dean Stockwell); He is a journalist of a certain reputation who came to New York to find a writing job for a liberal magazine. The owner, John Minify (Albert Dekker), introduces Philip to his elegant, beautiful niece, although a little fragile, Kathy (Dorothy McGuire), who has an idea of functionality – how about writing about anti-Semitism?

Director Elia Kazan writes in his autobiography that Jewish leaders from other major film studios held a meeting at which they pushed Hart to convince Zanuck not to make the film because they did not want to stir up anti-Semitism.
