Emma Byler can't wait for her sixteenth birthday and to experience a taste of freedom. With her Amish Rumspringa relaxing some of her usual restrictions, she's desperate to spend time with a special boy. But she fears tensions at home and her father's increasingly short-temper could make him pull back the reins. Sixteen years ago, Jacob Byler made a promise. But as his daughter's celebration draws near, he dreads the emotional upheaval she'll go through when she learns the truth. And all he can do is pray that God will grant him the courage he needs to come clean. As Emma tries to deal with her father's worsening behavior, she's forced to keep her own confidences. And Jacob reaches the breaking point when his son befriends a youth who could topple the whole house of cards.
