Anna is eager to begin a new chapter in her life as a Lancaster County tour guide in the picturesque area where her Plain grandmother once stayed. Anna wishes she could talk with her grandmother about those long-ago days, but the elderly woman suffers from Alzheimer's, and beyond a vague hint about an old stone wall, much about that time is a mystery. Thankfully, Martin Nolt, a handsome Mennonite, takes the young Beachy Amish woman under his wing for her training, familiarizing her with the many local highlights, including Peaceful Meadows Horse Retreat, which serves children with special needs. The retreat's mission so inspires Anna that she returns to volunteer, and she quickly strikes up a friendship with Gabe Allgyer, the young Amish widower who manages it.

As Anna grows closer to both Martin and Gabe, she finds herself faced with a difficult choice--one in potential conflict with the expectations of her parents. Will Anna find true love and the truth about her grandmother's past in Lancaster County? Or will she find only heartbreak?
