Three punk rockers from New York City—Grant, Biscuit, and Milo—are frustrated with their mundane urban lives and decide to leave their home in search of a new beginning. They pile into a Volkswagen Beetle and embark on a cross-country road trip to California. While passing through the desolation of the southwestern desert, their journey takes an unexpected turn when they encounter a violent gang led by the ruthless Missoula. In a brutal attack, one of the friends is murdered, leaving the remaining two traumatized and bent on revenge.

The duo teams up with a feisty, strong-willed woman named Jessie, who aids them in their quest. She teaches them survival skills and helps them navigate the unfamiliar territory. Guided by the memories of their fallen friend and fueled by the desire for justice, they steadily track Missoula's gang across the vast, empty landscapes of the American West. Throughout this treacherous journey, the friends grow closer, confront their fears, and discover inner strengths they never knew they had.
