The film centers on Annie (Kristen Wiig), a simple and single 30-something Midwestern girl (with poor dating track record) who is asked to be her best friend Lillian’s (Maya Rudolph) maid of honor.

However, having never done the job, she struggles to please the snobby, rich bridesmaids at every pre-wedding event.

And one of Lillian’s best friends is essentially the bridesmaid from hell (Rose Byrne) – who attempts to take over the maid of honor duties from the inexperienced Annie.
