Maggie (Greta Gerwig) has never sustained a relationship longer than six months - but desperately wants a baby. She solicits a sperm donation from a friend, but has hardly begun the artificial insemination process when she consummates a budding romance with John (Ethan Hawke), an unhappily married academic hailed as "the bad boy of fictocritical anthropology."
Maggie's rejuvenating enthusiasm lures John away from his brilliant but domineering Danish wife Georgette Nørgaard (Julianne Moore) and the two settle down to raise their daughter. Everything has gone according to Maggie's plan; so why isn't she happy, and what meddlesome scheme will she concoct next? Maggie's Plan is a charming, sophisticated and funny exploration of the unexpected complexities of modern romance.
