American Playhouse (1982) : 8x5

In St. Louis, circa 1950, Ben Griffin lives with his widowed mother and beautiful older sister, Dodie. The restoration of the family's affluence seems to hinge on Dodie's romances and hoped-for-marriage to a wealthy husband. But Dodie's ambivalence toward the rich and eligible Sonny confuses and upsets Ben. He wants to trust and believe in love, but worries that he may never find a girl to understand his romantic ideals.
