Advised by his son's school to up his game as a single parent, arrogant ex-baseball star, Rusty Reisse, takes a hiatus from his broadcasting career to spend the summer with his son.
Rusty hopes to bond with Tommy in rural Pine Grove. His plan blows up when Meg Gunderson, a brainiac schoolteacher, shows up with her son, claiming the house is hers. When police compare receipts, they discover Rusty and Meg have rented the same house.
A widow, Meg, schemes to get Rusty out. He's equally determined to send her packing. Although a war of words ensues, the boys become friends. Obligated to share the digs for the duration, they're forced to declare a reluctant truce.
While no longer openly hostile, they still snipe at each other, too stubborn to admit their growing attraction. When their vacation ends abruptly, will their chemistry vanish, too, with the summer sun and corn-on-the cob?
