Middle-aged Annie (Kristen Weiger Kristen Wiig) still does nothing and muddles through life. Her long-time boyfriend only regards her as a lover and has no plans to start a family with her. At this time, Anne's good friend Lillian (Maia Rudolph Maya Rudolph) is suddenly getting married and invites several female friends, including her, to form a bridesmaid group. Helen in the companion group (Rose Byrne Rose Byrne) has a deep family background and is exquisite in all aspects, making every effort to create a luxurious wedding for Lillian. Anne was dissatisfied with Helen's leading the wedding planning and went head-to-head with her everywhere, trying to tell Lillian about her deep friendship, but every effort made everyone unhappy and led to Lillian's dissatisfaction. At the same time, Annie also began to face many problems in her life. The appearance of traffic policeman Rhodes (Chris Odod Chris O'Dow) seems to open another window for Annie. Can Annie get rid of these difficulties and get on the right track of life?
