Kindergarten teacher Emily organizes a first-time gathering for “Daughters for Aryan Unity,” a collective of white supremacist Caucasian women. The group consists of ex-convict Leslie, small grocery store owner Kim, and disgruntled retail worker [Marjorie]. During the meeting, held in a church, the members voice their grievances against various groups, including immigrants, minorities, Jews, feminists, and organizations like Black Lives Matter. However, the pastor of the church grows uncomfortable with the discussion and ultimately forces Emily to vacate the premises.

Determined to carry on, Emily invites the others to her home, which they agree to. The four women head to Kim’s store for refreshments. While Emily browses the wine selection, Asian-American sisters Anne and Lily arrive, unaware the shop is closed. When Kim refuses them service, Lily confronts her, and Emily intervenes. In an attempt to ease the tension, Anne tries to mediate but ends up being coerced by Emily into buying the most expensive item in the store. As the sisters leave, Marjorie escalates the confrontation with Anne, which leads to violence. In a shocking twist, Kim pulls a pistol and forces the sisters out at gunpoint, while Lily insults Emily regarding her brother, who is incarcerated for raping Anne.

Soon after, Emily’s husband Craig arrives, aiming to calm things down. However, Leslie proposes a drastic plan to vandalize Anne’s home and steal her passport. Initially reluctant, Craig is pressured by Emily to participate. She reveals personal details about Anne’s living situation, raising Craig’s concerns about Emily’s obsession.

Upon arriving at Anne’s house, chaos ensues as the group vandalizes the property. They are soon caught off guard when Anne and Lily return home. Confused and panicked, the intruders bind and gag the sisters at gunpoint as they debate their next move. Disturbed by the unfolding events, Craig decides to leave, unable to condone the situation.

As tensions rise, Leslie suggests they cover their tracks and intimidate the sisters into silence. In a brutal turn, Leslie and Marjorie physically assault Anne and Lily, force-feeding Lily until she begins to choke. They realize too late that Lily has a peanut allergy, and tragically, she dies after an attempt to use an epinephrine injector fails. This prompts discord among the intruders, as Kim and Marjorie want to flee, while Emily insists on erasing any evidence.

In an even darker twist, Leslie proposes to stage the incident as a sexual assault to distance themselves from the crime committed by women. Disturbingly, she proceeds to sexually assault Anne with a carrot, while the others hurriedly attempt to clean the scene. To ensure there are no witnesses, Leslie suffocates Anne using a pillow.

After disposing of their cleaning supplies and the bodies of Lily and Anne in a bag, the group makes their way to a nearby lake. They venture out on a boat and dump the evidence overboard. Unbeknownst to them, Anne, still alive, manages to free herself after they leave.
