In an affluent area of downtown New York City, a Sunday evening dinner party is taking place. Hosted by Libby, an insecure thirty-something widow who lost her husband in an unfortunate accident, her guest of honor is downstairs neighbor Alice, a successful novelist, and Alice's lesbian lover, Boo, a family therapist. The other guests are Griever, Libby's best friend from group therapy; Norbert, Libby's gentle skydiving instructor; Tom, an old high-school boyfriend of Libby's now working as a jazz musician and composer, and Emily, Tom's current live-in girlfriend.
