Teenage lovers Jordan White and Amy Blue embark on a night out, unexpectedly picking up a charming drifter named Xavier Red during their drive home from a club. Renaming him "X," the trio's plans take a drastic turn after a seemingly simple stop at a convenience store leads to unforeseen chaos. In a tragic accident, X kills the store's owner, throwing them into a whirlwind of panic as they seek refuge in a nearby motel to evade the law.
In a moment of intimacy, Jordan and Amy indulge in a passionate encounter inside the bathtub, while X, in a seemingly voyeuristic fashion, observes them from outside. The tension escalates when X learns from a local news broadcast about the store owner's wife, who brutally took the lives of her children before ending her own life. This disturbing revelation gives X a false sense of security, believing that they are not likely to be suspected by the authorities.
As their night unfolds, Amy finds herself in bed with X, despite their initial animosity toward one another. Tensions between the two men rise when Jordan discovers this unexpected liaison, igniting complicated feelings including a budding sexual attraction between them. Their escapade through the chaotic streets of Los Angeles is punctuated by a series of absurdly violent encounters—each transaction they make at shops amusingly totals $6.66—during which they are mistakenly linked to Amy's supposed former lovers, much to their dismay. This catalyzes interest from the FBI, heightening the pressure on the trio with multiple groups expressing a desire to find Amy, even voicing sentiments of wanting her dead.
Among the confounding misidentifications, a fast-food worker mistakenly refers to Amy as "Sunshine," and another character portrayed by Parker Posey miscalls her "Kitten." The three eventually take refuge in an abandoned warehouse, where a surreal encounter unfolds as they engage in a shocking threesome. However, the night takes a dark turn when, during a bathroom break, Jordan and X are ambushed by a group of neo-Nazis. One of the attackers has previously confused Amy with his ex-girlfriend "Bambi." In a brutal scene, the gang violently assaults X and horrifically assaults Amy on an American flag, culminating in a gruesome attack on Jordan.
In a shocking twist, after Amy breaks free from her captors, she manages to turn the tables, killing the neo-Nazis with their own weapon and fleeing with X, leaving a broken Jordan behind. As the film concludes, Amy and X find themselves aimlessly driving down an empty road, encapsulating their chaotic journey. The screen fades to black as X offers Amy a Dorito—a seemingly trivial gesture against the weight of the night's events—while she remains unresponsive, and the credits begin to roll.
