Abandoned

When Mary and Hezekiah discovered an abandoned baby on their property, they did what they considered best, which was to keep her circumstances a secret and raise her themselves.
When Rose turns eighteen and is weeks away from marrying James, she discovers how she came to live with Mary and Hezekiah. Angry that she's been lied to her entire life, Rose tells James she cannot marry him and leaves her Amish community.
Devastated that his future wife has cancelled their wedding, James sets about to look for Rose's birth parents hoping that finding them will help Rose change her mind.
