Gemma's life is about to take a dramatic turn. Living in London, she faces the sudden loss of her American fiancé, Nathan, just before their wedding day. Nathan's passing forces Gemma, who has always been skeptical of modern marriage, to reassess the meaning of a lifelong commitment. With a push from Nathan’s free-spirited and unpredictable sister, Audrey, Gemma makes the bold decision to proceed with the wedding. However, to say "I do," she must navigate public opinion, legal hurdles, and even her own family's objections. This unconventional romantic comedy is brought to life by a dynamic ensemble cast, including Aisling Bea, Colin Hanks, and Billie Lourd. Directed by Daniel Reisinger in his feature debut, the film uses Gemma’s quest to challenge societal norms and offers a vibrant exploration of London, the city where they lived and loved. Thematically, it rebels against the traditional British 'stiff upper lip' mentality, delivering a heartfelt message that there is no 'right' way to grieve, and that love can truly conquer all.
