Hannah's dating app goes badly and before Christmas she is asked by her partner in the company to go home to think about how they can save the company. To her father's delight, she follows the advice. Once there, she discovers that a dating event is being arranged where you exchange letters with a stranger (brokerage takes place via the local post office) until Christmas when you reveal who is who. Hannah convinces her father to participate but he only participates if Hannah also participates. Hannah begins to exchange letters and her anonymous pen pal gains her interest. At the same time, she reconnects with Sam, her old boyfriend from school days.
A good romantic film even if you get weary of the technology hostility. However, style points are awarded for Hannah naming her home robot (like a Google Home) Marvin.
