The Invite

In San Francisco, failed musician Joe arrives home from his job as a jazz band teacher at a conservatory to discover his stay-at-home wife Angela has invited their upstairs neighbors, divorcée Piña and widower Hawk, over for dinner at their apartment. Joe and Angela's marriage is rocky and they bicker constantly, most recently over the loud sex sounds they often hear from upstairs. Joe plans to confront the couple, but Angela, who is desperate to impress the neighbors, demands he keep calm and quiet.

Piña and Hawk arrive at the apartment as Joe and Angela are mid-argument. Unprepared to host a dinner party, Angela makes several awkward mistakes, such as not having any wine and not checking Piña's dietary restrictions. Meanwhile, Joe openly antagonizes the couple, but is surprised to see they are impressed by his brutally honest nature. The group eventually warm up to one another, although Joe still resents his neighbors for their noise and is troubled when he learns Hawk has seen Angela naked through a window.

Later that night, Piña and Hawk apologize for the noise they make during sex and reveal to Joe and Angela that they participate in sex parties which is the reason for the noise; Joe and Angela are titillated by this discovery. Piña admits that she and Hawk came to the dinner party hoping to invite Joe and Angela to have group sex with them. Joe and Angela are eager, but Piña, who is a sexologist, is unsure after seeing the couple fight throughout the night. Instead, they decide to swap partners. However, Angela is too nervous to initiate sex with Hawk while Joe falls while dancing with Piña and hurts his back.

Another argument erupts between Joe and Angela, and he berates their neighbors. Piña gets the couple to talk about their relationship, and learns of the resentment they have to each other and the fact they have not had sex in a year. Piña suggests the couple should separate instead of sticking together for the sake of their daughter, Maggie, or find a way to reframe their relationship, as the current status appears to have run its course. Angela and Joe seemingly agree to separate, and discuss their next moves, but upon returning from the kitchen, discover Piña and Hawk have left. Joe returns to his office and plays his piano, which he had previously refused to play, with Angela eventually joining him.
