Liv and Emma are best friends. Liv is a successful lawyer who has everything she ever wanted at a young age: a perfect job and a perfect boyfriend. Emma is a teacher, a gentle girl who always takes care of others but often forgets to take care of herself. When they were little girls, they often played the game of pretending to be brides in the attic, and since then, they have been planning the details of their respective weddings. At the top of their "must-have" list for their weddings is a place that every bride in New York dreams of having their wedding: PLAZA HOTEL.
Unexpectedly, their boyfriends proposed to them almost simultaneously. They promised to be each other's bridesmaids, accompanying their good friend down the beautiful aisle. As their dreams were about to come true and they were set to live happily ever after with their respective princes, an unexpected mistake by the priest disrupted their plans - they would now have to get married on the same day. The long-standing friendship between Liv and Emma faces its ultimate test. With neither able to convince the other to change the wedding date, these two best friends nearly become sworn enemies for the sake of their bridal dreams. Guests, makeup, attire... Everything becomes a point of competition or sabotage between the two. The hostility reaches its peak on their wedding day. Will these two former best friends be able to have the perfect weddings of their dreams?
