Four women, four friends, four destinies... After years of fake weddings they staged in their backyard as children, the four friends have now acquired a remarkable ability: to perfectly organize the most important day in every couple's life. From the smallest detail of the wedding cake to the last petal of the bouquet and from the correct lighting angle to the seating of every guest, the four friends guarantee that this wonderful day will be filled with wonderful memories that will last a wonderful lifetime. Mac Elliot, with various magazine covers to her credit, is in her element when holding a camera, ready to capture joyful family moments. Moments she always dreamed of herself, as she never had the luck to experience them. Her father replaced his family with another, and her mother gets involved in Mac's life at the slightest excuse. All this weighs on her and stresses her out on the eve of an important wedding she has undertaken with her friends. Without knowing it, this wedding between two people unknown to her will change her life forever. Carter Maguire, the distant brother of the bride, is certainly not her type. But something about him makes Mac believe he is the right one to help her forget the daunting responsibilities of her job and the troubles of her family. Unexpectedly, what she thought would be fleeting seems to have potential. With the help of her three friends and partners, she will learn to create her own wonderful memories.
