In Depression-era New York, painter Eben Adams despairs at his lack of success. One cold winter evening in Central Park, he meets enigmatic, old-fashioned Jennie Appleton, who captures his fancy when she asks him to wait for her to grow up. Soon after, Eben sells a sketch of Jennie to kindly art dealer Miss Spinny and, as he meets the oddly mutable Jennie in fleeting moments, begins to realize they share a special destiny.
