A homeless drifter arrives in a city overrun by crime, corruption, and violence. The streets are controlled by a ruthless crime lord named Drake, who, along with his sadistic sons, terrorizes the citizens with impunity. Witnessing one atrocity after another, the drifter dreams of buying a lawnmower to start an honest life. However, his path changes dramatically when he decides to take a stand against the chaos after a violent encounter. Discovering a pawnshop during a particularly brutal moment, he forgoes his savings for a lawnmower and instead opts for a shotgun, vowing to clean up the city.

Equipped with his newfound weapon, the drifter begins to wage a one-man war against Drake's gang and the corrupt police force aiding them. He forms an unlikely alliance with Abby, a prostitute with a heart of gold, who becomes both his protégé and moral compass. Together, they confront the pervasive evil of the city, facing increasingly violent and dangerous adversaries. Their relentless pursuit of justice triggers a series of brutal confrontations, instilling fear in the hearts of the oppressors and sparking hope among the terrorized citizens. As the war intensifies, the drifter's mission grows ever more perilous, leading to a climactic showdown that will determine the fate of the city's future.
