It is 1947 and in the aftermath of World War II halcyon days have not returned to Magrit, Minnesota, where the veterans have failed to come home. The men haven't died; they've just moved onto greener pastures, rejecting the local women, who served the war effort in the Scientific Kitchen of Margaret Mill. The mill was founded by Henry Collins, the man responsible for Sweetwheats, the world's first puffed and sugar-coated cereal. As part of a publicity campaign, Henry creates the Sweetwheats Sweethearts all-girl baseball team, convincing the mill girls that this will help them find husbands.
