The annual state fair was the biggest, most fabulous, most anticipated event in mid-20th century Iowa. There were hogs to judge, pies to bake, pickles to pickle; and music was in the air.... most of the time. The Frake family is alive with excitement and promise. Pa Frake (Charles Winninger) wants Blue Boy, his special boar, to win best in show. Ma Frake (Fay Bainter) works tenaciously on her mincemeat and sour pickles. Restless Margy Frake (
Jeanne Crain) hopes to meet the man of her dreams so she won't have to settle for the dull but suitable boy-next-door. Amidst the sounds and colors of the midway, the magical music of Rodgers and Hammerstein, and the sturdy downhome values of America's agrarian community, the Frakes make some missteps, face some obstacles, but ultimately find "local fame," love, and contentment at their state fair.
