The Stolen Valley tells the story of Lupe Reyes, a young Mexican-Navajo woman on a journey to save her sick mother. Living in a modern Western town with her family, Lupe sets out after learning her estranged father may hold the key to paying for an expensive medical treatment.

Along the way, she coincidentally aids an outlaw cowgirl fleeing criminals and finds her father is more dangerous than she imagined. As Lupe discovers deeper secrets about her cultural heritage and family history, she must fight for the rights of her people against the exploitative villain threatening the Native lands she holds dear.

The film aims to present indigenous perspectives and issues of land rights and injustice against Native Americans. However, while its heart is in the right place, The Stolen Valley ultimately struggles to fully convince as a movie, with thin characters and contrived plot points weakening its lofty goals.
