Travelling on an overnight train from Miami to New York in the summer of 1944, furloughed paratroopers Red (Tab Hunter) and George (Jack Warden) make the acquaintance of Kay (Sophia Loren) and Jane (Barbara Nichols), who are also on their way to the Big Apple under the protective eye of Harry Corwin (Keenan Wynn), an assistant to big-shot industrialist A.L. (George Sanders).
A.L. has been keeping Kay as his mistress, while Jane is an extra “friend” for others whom he has to influence.
Kay and Red are attracted to each other, but after a night together, she tries to break up with him, hoping he will go home to visit his family in Vermont before he is reassigned overseas.
But Red has fallen in love and persuades Kay to spend more time with him, while Jane and George also get to like each other.
A.L. is disturbed by their relationship and even proposes marriage to Kay. Red has also proposed, and he asks her to join him on his visit home to introduce her to his folks.
Jane, meanwhile, has been propositioned by a general who wants to set her up in an apartment in Washington, and when Jack doesn’t ask her to marry him, she leaves. After a tender goodbye to A.L., Kay rushes to be reunited with Red.
The script is full of down-to-earth dialogue and situations and offers some torrid romance sequences and attractive background settings in New York City.
The screenplay by Walter Bernstein is based on a story by Robert Lowry.
