In Lancaster, Pennsylvania, fine Amish lad Samuel is devoted to his arranged betrothed, Hannah Yoder, who turns 18 and joins a few peers, like Isaac, on Rumspringa, the traditional taste of 'wicked' life outside, in this case in Los Angeles. Hannah is the only one who doesn't seem to enjoy the trappings of modern free youth; she avoids parties but is charmed by Josh, a more mature young intellectual who shows her the simple joys of modernity. They become lovers, but unlike Isaac, she doesn't simply stay behind but insists to part properly with her family and Samuel. But once she's home, she can't quite make the break. Samuel finds out that she's pregnant and offers to marry her and accept and raise her child as his. Then Josh arrives, demanding a decision.
