The Perfect Wedding Match

Maisie Jacobs is the developer of a matchmaking app, RSVP Plus One, which brings two people together for an event. She does an interview with journalist Luke Penzer, but he is critical of the app and writes a negative article about it. Maisie's sister is getting married soon, and Maisie, who is single, uses the app to find a date to the wedding. Due to her co-worker's mistake, she gets matched with Luke. Despite Maisie's protests, Luke insists on staying and is welcomed by the rest of the family. Over the next few days, the two get to know each other better while preparing for the wedding. Luke tries to show Maisie that he's a good guy, but she has a tough time getting past his bad first impression.
