After a divorce, Nancy moves to North Carolina and takes a job as a caregiver for older patients who are in poor health. The work is rewarding but challenging, and to help her unwind after long days, a roommate introduces her to Korean television dramas. She becomes a fan of one actor in particular, Paul Ahn, and follows him on social media. So she is thrilled when she receives a Facebook message from someone claiming to be Paul. They exchange messages, and the relationship quickly becomes romantic. Paul invites Nancy to visit him, but there is a catch: She must pay a reservation fee of $18,500. As she prepares for the trip, he asks for more and more money for travel expenses, leading Nancy to wonder if he really is who he seems.
