Daphne Wilder (Diane Keaton) is a mother whose love knows no bounds or boundaries. She is the proud mom of three daughters: stable psychologist Maggie (Lauren Graham), sexy and irreverent Mae (Piper Perabo) and insecure, adorable Milly (Mandy Moore) -- who, when it comes to men, is like psychotic flypaper.
In order to prevent her youngest from making the same mistakes she did, Daphne decides to set Milly up with the perfect man. Little does Milly know, however, that her mom placed an ad in the online personals to find him. Comic mayhem unfolds as Daphne continues to do the wrong thing for the right reasons...all in the name of love.
In a hilarious battle of strong wills, the mother-daughter dynamic is tested in all its fierce, wacky complexity. The girls help Daphne finally discover the truths and impossibilities of motherly love, all while trying to answer the questions: where does it begin and where should it end?
