Annie (Kristen Wiig) and Lillian (Maya Rudolph) have been besties for ages, so it makes sense for Annie to play maid of honour for Lillian's upcoming wedding. "Pick me" girl Helen (Rose Byrne) isn't really one to stand on the sidelines. As Lillian's new good friend, she can't help but try to take over maid of honour duties, even though she's just a bridesmaid. Of course this leads to some drama between Annie and Lillian — after a botched flight to Las Vegas in which Annie gets high and claims there's a Colonial woman churning butter on the wing — and Helen is happy to step in and take over Annie's job. It's another lighthearted, funny movie with women at the forefront, with a special emphasis on friendship like in Legally Blonde.
