Dogville is a tiny American town nestled in the Rocky Mountains, boasting a solitary road leading up to it, but with no real outlet aside from the towering peaks. The film opens with a prologue introducing us to around a dozen of its fifteen residents, depicted as charming yet flawed individuals, whose imperfections are easily forgivable.
The viewer sees the town through the lens of Tom Edison, an aspiring writer who often finds himself procrastinating by attempting to rally his fellow townsfolk for meetings centered on "moral rearmament." Tom harbors ambitions to step into the shoes of his aging father, aiming to become the town's new moral and spiritual compass.
It is during one of his ventures that he encounters Grace, a woman fleeing from dangerous gangsters after an apparent attempt on her life. Grace, possessing both beauty and modesty, is eager to escape, yet Tom convinces her that the mountains are impassable. Just as they converse, the gangsters draw near the town, prompting Tom to quickly conceal Grace within a nearby mine. When one gangster inquires about her whereabouts, Tom lies and declines to reveal anything, leading the gangster to offer him a reward should he have any news on the woman.
Motivated by the chance to showcase the town's moral values, Tom decides to present Grace as a "case study" at his next meeting, encouraging the residents to step up and prove their commitment to helping a stranger. Despite initial skepticism, Tom proposes that Grace should be granted two weeks to earn the townspeople's affection.
Per Tom's suggestion, Grace starts assisting with local chores—visiting the lonely, blind Jack McCay, managing the small town shop, and caring for the children of Chuck and Vera. Although there is initial reluctance, the townsfolk gradually accept Grace's contributions, as her assistance brings warmth and ease to their lives. Over time, she grows closer to the residents, including Jack, who pretends not to be blind; Grace cunningly leads him to admit the truth, earning his respect.
As the two-week deadline approaches, the townspeople vote unanimously for Grace to remain in their midst. However, the mood shifts when the police arrive to post a "Missing" flyer with Grace's likeness at the mission house. While spirits remain high, a cloud looms over the town during their July 4th celebrations. After Tom awkwardly professes his love for Grace—who has transformed the town for the better—the police return once more, this time with a "Wanted" poster, branding Grace a suspect in a bank robbery. It is widely acknowledged that she must be innocent, as she has been engaged in her daily chores throughout the incident.
Despite this, Tom insists that for the safety of the town—now harboring a felon—Grace needs to increase her contributions in exchange for less pay. The once voluntary arrangement starts taking on a coercive tone, which leaves Grace feeling uncomfortable. Nevertheless, eager to please Tom, she reluctantly agrees.
The situation deteriorates as Grace struggles under her newfound burden. Mistakes ensue, and the townspeople's frustration is misdirected at her. Male citizens begin to make unwelcome advances, while female residents display growing hostility. Even the children partake in this disturbing dynamic: Jason, the young son of Chuck and Vera, pressure Grace into spanking him, to which she ultimately complies after much coercion. It is not long before Chuck assaults Grace, exposing her vulnerability to profound exploitation.
When Tom discusses the prospect of escape with Grace, Vera turns on her, blaming her for both Jason's spanking and Chuck's attack. Seeking retribution, Vera threatens to destroy the porcelain figurines made by the town shop, which Grace had acquired with her meager earnings. Torn between the memories of teaching stoicism to her children, Grace begs for mercy. Vera, however, beats her down, destroying the first two figurines. As Grace fails to contain her tears, Vera claims the rest, smashing the last of them. With this symbolic loss of belonging, Grace realizes she must flee. Together with Tom and Ben, the freight driver, she attempts to escape in his apple truck, only to be assaulted by Ben and subsequently returned to the town.
Determined not to let her slip away again, the townspeople conspire against her. The money used to pay Ben was taken without Tom's father's knowledge, and Grace faces accusations of theft. Tom opts not to speak up, explaining that it's the only way he can protect Grace without raising suspicion. At this juncture, Grace's status as a slave is conclusively established: she is forcefully collared and chained to a heavy iron wheel, rendering her incapable of escape. To further strip her dignity, a bell is affixed to her collar, announcing her presence throughout the town. Intriguingly, Tom remains the sole male citizen who does not take advantage of her.
Matters culminate in a night assembly where, with Tom’s prompting, Grace recounts the torment she has suffered at the hands of the townspeople. Ashamed and in utter denial, they ultimately decide to cast her out. When Tom reaches out to console Grace after this betrayal, he attempts to engage with her intimately, having been the only man in town not to have crossed that line. However, Grace denies him, which fuels Tom's fury—not just at her rejection, but more at his realization of how low he might stoop to engage with her like the others.
In a moment of desperation, he calls upon the mobsters, and, with community backing, proposes that Grace be imprisoned in her shack. When the gangsters finally arrive, they are received warmly by Tom and an ad hoc committee of townsfolk. It is during this confrontation that we learn Grace's true identity: the daughter of a formidable crime leader, she fled from a life she could no longer bear.
Her father, confronting her in his lavish limousine, chastises her for being condescending toward others regarding their moral failings. Initially resistant, Grace reevaluates her perspective of the townsfolk and acknowledges that condemning them by her stringent standards would warrant their extinction. This internal struggle leads her to align once more with her father's dark legacy, ultimately commanding the obliteration of the town and its residents.
She orders Vera to witness the murder of her children, placing her in a perverse position where withholding tears is a dire test. The film reaches its harrowing climax with the town engulfed in flames, and the citizens face a brutal end by gangsters under the direct orders of Grace. In a chilling finale, she takes Tom's life personally, marking his death amidst the chaos. As the ashes of Dogville settle, Grace spares only one soul—the loyal dog, Moses, who symbolizes the lone innocent amid the town's decay. Ironically, the only creature that hasn't betrayed her becomes the sole survivor in the ravaged remains of her former community.
