Eva (Julia Louis-Dreyfus), a masseuse, a mother of a teenage girl and a divorcee attends a party in Pacific Palisades with her friends, married couple Will (Ben Falcone) and Sarah (Toni Collette). She meets a poet, Marianne (Catherine Keener), and Will introduces Eva to his friends, Jason (Phillip Brock) and Albert (James Gandolfini). After the party, Albert asks Will for Eva's number and though hesitant, due to the lack of physical attraction, Eva agrees to go on a dinner date with Albert, which goes well. Marianne contacts Eva for a massage, Eva takes an immediate liking to Marianne, and they become friends.
Eva finds herself more and more fond of Albert and they have lunch with his teenage daughter, Tess (Eve Hewson), who, like Eva's daughter, is graduating from high school and moving away to attend college. A few days later, Eva goes to her massage appointment with Marianne and realizes that Albert is Marianne's ex-husband after she tells her a story about how he eats guacamole - the same story Albert told her. Tess then arrives at the house and Eva's suspicions are confirmed. Marianne tries to introduce Eva to Tess, but she hides behind a tree to avoid the meeting. Eva continues seeing Albert, keeping her friendship with Marianne a secret; likewise, she does not tell Marianne she is seeing him.
Eva encourages Marianne to complain about her ex-husband Albert so she can identify potential problems in her relationship with him. To the encouragement of Eva, Sarah and Will invite her and Albert to a dinner party, which goes badly after Eva begins finding fault with Albert, which upsets him. At another appointment with Marianne, Eva is exposed when Albert arrives to drop Tess off at her mother's. He is angry that Eva kept her friendship with Marianne a secret, and breaks up with her.
Eva and her ex-husband take Ellen to the airport for her flight to college. A few months later, on Thanksgiving Day, Eva drives by Albert's home and stops in front of the house on her way to pick up Ellen from the airport. He sees her and she awkwardly waves. He eventually comes outside, to Eva's surprise, and sits with her on the porch and they begin to renew their relationship.
