Harry Sanborn is a wealthy New York City
record company owner who only dates women under 30, including his latest girlfriend, Marin Klein. The two drive to her mother's
Hamptons beach house, expecting to be alone. However, Marin's mother,
playwright Erica Barry, and aunt Zoe arrive unexpectedly. After an awkward dinner, the night turns disastrous when—during
foreplay with Marin—Harry has a
heart attack and is rushed to a hospital. The attending doctor, Julian Mercer, tells Harry to stay nearby for a few days, so he reluctantly stays with Erica. Complicating matters, Julian is a fan of Erica's work and is clearly attracted to her. Erica and Harry's personalities clash and create awkward living arrangements at first, but they soon find charming qualities in each other and begin to form a connection. Harry's relationship with Marin and Erica's budding relationship with Julian become obstacles to their growing attraction. Marin tells her mother she will break up with Harry, but he ends things first. Harry and Erica spend more time together and eventually have sex. Julian tells Harry he has improved enough to return to the city. He and Erica share an awkward goodbye, as despite their strong feelings, Harry is clearly hesitant to enter into a relationship. Marin receives news that her father and Erica's ex-husband, Dave Klein, is getting remarried to a doctor only two years older than Marin. Though Erica is unaffected by the news, Marin is devastated and pressures her mother into accompanying her to a dinner. At dinner, Erica sees Harry at another table with a much younger woman. An argument follows and Erica confesses that she is in love with him, but when Harry does not seem to reciprocate, Erica ends things between them and leaves. Harry has what he believes is another heart attack, but in the emergency room he is told it was a
panic attack. Devastated, Erica returns home where she cries almost nonstop for several weeks. She pours her heartbreak into a new play about a woman who falls in love with her daughter's boyfriend, titling it "A Woman to Love," a phrase Harry had used to describe Erica. Harry hears about the play and rushes to the theater, where it is being rehearsed. Despite her denials, it is obvious that Erica has used the most personal details of their affair in the play. When Harry tells her he still cares about her, she rebuffs him. After learning his character dies in the play, he suffers another panic attack. At the hospital, Harry is told he needs to de-stress, and relocates temporarily to the
Bahamas. Six months later, Erica's play is a huge success. Harry pays Marin a visit to apologize for any past disrespect, and discovers she is happily married and pregnant. Marin tells him Erica is in
Paris celebrating her birthday. Harry flies there and surprises Erica at her favorite restaurant, where he tells her he has been reaching out to all the young women he had affairs with in an attempt to atone for his heartless behavior. Julian, whom Erica is now dating, appears. Harry, Erica and Julian have dinner together, and part amicably outside the restaurant. While Harry gazes in heartache over the river
Seine, Erica arrives. She tells him Julian realized she still loves Harry and has decided to step aside so they could be together. Harry tells Erica that at age 63, he is in love for the first time in his life, and they embrace. A year later at a restaurant, the now-married Erica and Harry are out with Marin, her husband Danny and their new baby daughter, celebrating life as a loving family. == Cast ==
