Maggie’s Plan(2016)

Because she doesn’t like long-term relationships but wants to be a mother, Maggie (Greta Gerwig) decides to artificially inseminate herself with the sperm of a hipster friend from college.

At the university she works at, she meets John (Ethan Hawke), a professor who has given up writing his book to support his academic wife, Georgette (Julianne Moore).

As Maggie and John grow closer, he realizes she brings out the best in him in a way that Georgette doesn’t.

Three years later, he is now married to Maggie and they live with their three-year-old daughter. Over time, Maggie begins to feel unappreciated by John, the same way he had felt in Georgette. She devises a plan to get him to go back to Georgette which she agrees to, rekindling their relationship during a conference in Quebec.

Maggie gives John’s blessing to return to his ex-wife and the three all live in harmony with their three kids (Maggie’s daughter and the son and daughter of Georgette and John).

As the film ends, it is hinted that Maggie’s daughter is actually from the man who donated his sperm, who happens to catch her eye for the first time.
