Starring Haley Lu Richardson and Owen Teague, it about siblings returning to their family's ranch in Montana after their father falls into a coma.

Estranged, twenty-something, half-siblings Cal and Erin return to the vast Montana ranch they once called home after their father has fallen into a coma and is now on life support.

Kenyan immigrant nurse, Ace (a nickname he uses since people in the United States have trouble pronouncing his real name) has been providing life-sustaining care to the siblings' father.

Erin, who remains angry about the abuse, plans to take the family's elderly horse, Mr. T, back to her home in Hudson Valley, New York.

Cal explains to Ace that, seven years ago, his father was a lawyer who helped cover up a toxic incident at the Copperhead open-pit mine.

Ace struggles to keep his patient alive, enlisting Erin to manually pump a bag valve mask to keep her father breathing.

The film was shot in Paradise Valley south of Livingston, Montana during a period of six weeks from November to December 2020 under strict COVID-19 protocols.
