Old Order Amish Ivy Zook is wrestling with her need to shed her community's ways so she can grow the business of her dreams: planning parties. As long as she's stuck living without modernization, she can barely get her business on its feet. But if she leaves too soon, she'd cause trouble for her sister, Holly, who is planning her wedding to Joshua Smucker. All of their plans become twice as complicated when an old car crashes into the storefront of Greene's Pharmacy, carrying a Swartzentruber (ultra-conservative sect) Amish man, Arlan, and his very ill sister. 

The Zooks take in Arlan and Madga, tending to the woman's illness and Arlan begins helping around the family farm. Ivy and Arlan are on different tracks, one wanting to leave her community and the other to return to his. But both young people are trying to discover what God has in store for their futures and what miracles might lie around the corner this Christmas season.
