Beatriz, portrayed by Salma Hayek, is a Hispanic woman in her late forties who wakes up from a vivid dream in which she finds herself in a rowboat amidst a mangrove swamp, confronted by the sight of a little white goat on the shore. After tending to her two dogs and a brown goat that she keeps in her bedroom, she encourages them to quiet down. Her day begins with mediation and lighting candles at an altar adorned with photographs of a man and the little white goat.
Beatriz drives her aging Volkswagen, which struggles to start, from her humble home in Los Angeles to a local cancer center where she provides treatments like massage, aromatherapy, and breathing exercises for patients. In a rush, she hurries to a client's residence in Newport Beach, Orange County, arriving a bit late to the extravagant house where her client, Cathy, played by Connie Britton, is hosting a gathering for her husband's business associates that evening.
During her massage for Cathy, the two women converse about Cathy's daughter, who Beatriz had previously treated during her battle with cancer. This talk evokes a deep sadness in Beatriz as she reveals her concerns regarding a neighbor who has lodged multiple noise complaints and has even requested that she part with her goats, suspecting that this neighbor may have killed her beloved white goat.
After the massage, Beatriz's car refuses to start. When Cathy unexpectedly invites her to stay for the dinner party, she faces a bit of resistance from her husband, Grant, played by David Warshofsky, who is concerned that they are hosting significant business guests. However, Cathy's insistence that Beatriz is part of their circle prevails.
The first pair to arrive are Alex and Shannon, portrayed by Jay Duplass and Chloë Sevigny, who discuss Alex's recent triumph in lobbying for a development approval by the California legislature. An older couple, Doug and Jeana Strutt, played by John Lithgow and Amy Landecker, receive enthusiastic welcomes from Cathy and Grant, with Beatriz sadly lingering in the background, feeling overlooked.
As the evening progresses, Beatriz attempts to engage with the guests but finds herself marginalized, especially when the men and women separate to mingle outdoors. Cathy defends Beatriz, highlighting her compassionate nature and healing talents, but Beatriz's discomfort grows as she overhears a cruel exchange about a celebrity. In a vulnerable moment, she confides to Cathy about the trauma of her past—being separated from her family as a child and losing her husband under mysterious circumstances.
When Beatriz learns that her friend won't be able to assist her until the following morning, Cathy extends an invitation for her to spend the night in her daughter's vacant room. However, as they reconvene for dinner, tensions rise. Doug crudely interrupts Beatriz, questioning her immigration status and dismissively asserting that society needs people like him—wealthy developers who create jobs.
Beatriz reflects on the devastation her hometown in Mexico faced due to failed developments and directly confronts Doug, suspecting his company could have been responsible for the destruction of her community. As the night unfolds, the conversation takes a disturbing turn when Doug brags about hunting, sharing a photo of a rhinoceros he killed on a safari, provoking outrage from Beatriz. She boldly labels his actions as disgusting and retreats from the living area.
After sipping wine and researching Doug on her phone, discovering damaging information about his controversial dealings, Beatriz retrieves a guitar and offers to sing a heartfelt song as an apology. However, she uses this moment to criticize the complacency of those in the room, declaring that the earth is dying and they are not immune to its repercussions, regardless of their gated communities.
After an intense confrontation, Grant forcibly removes Beatriz from the party, calling a tow truck to take her home. As she nervously awaits her ride, she fixates on Doug, witnessing him in conversation before an unsettling thought occurs. She contemplates an act of violence as the night spirals further out of control. Just as the climactic confrontation begins to unfold in her mind, she snaps back to reality—realizing she has not harmed Doug, but rather is a bystander in her own destructive fantasy.
Following the surreal night, Beatriz escapes the scene, only to find herself drawn to the ocean. With a heavy heart, she walks into the waters, the waves swallowing her as the guests release sky lanterns into the night. The narrative draws to a close with a haunting image—beneath the surface of the water, we are transported back to the mangrove swamp from Beatriz's dreams, encapsulating her profound sense of loss and longing.
