Kurt and Chloe are a carefree couple celebrating their wedding with their closest friends at Kurt's family vacation home in rural New Hampshire. The guest list includes Mia’s longtime friends: Beth, a gifted but directionless writer; Mia, a recently divorced single mother who's hesitant about attending a wedding; and Joe, Mia’s best friend, dealing with the aftermath of a painful breakup. As the weekend approaches the wedding, alcohol flows freely, old friendships are challenged, and new connections form.
