Roxy Callahan is the private chef to one of the richest, most capricious, calorie-counting wives in Hollywood. After a small dairy misunderstanding ruins her perfectly-built career in one fell swoop, Roxy returns home to upstate New York to help her hippie mother take care of the family diner.

When local farmer, handsome Leo Maxwell , delivers her a handful of homegrown walnuts, Roxy begins to believe that spending a summer back home might not be so bad after all. Leo is an ardent supporter of the eco-friendly slow food movement and loves to enjoy every moment, this applies to everything. Roxy is determined to return to the West Coast immediately after the end of the summer, but will the hum of serene fireflies and her own Almanzo Wilder be able to force her to stay in her native land?
