Before she knows what's happening, she finds herself in the tangle of small-time life complete with unrequited love and a mean girl with an agenda.

Between navigating those unexpected turn of events, she stumbles into a bovine secret and life-long rivalry that turn the town upside down and her peaceful existence into a mystery of epic proportions.
