Corrupt detectives and mob heirs brutally assault and kidnap an innocent college girl, dragging her to an infamous private brothel island for the ultra-wealthy. They believe her mother is merely a helpless, broke dockworker who can be beaten and tossed into the street without consequence. But that humble mother is actually Black Mamba, the most feared female crime lord who once ruled the entire North American underworld. Shattering her peaceful retirement, Black Mamba digs up her sealed arsenal and marches alone into the city’s most guarded syndicate compound. Displaying her legendary serpentine totem, she reduces arrogant mafia bosses to trembling wrecks on their knees. Within hours, 100,000 fully armed underworld loyalists emerge from shadows across the continent, locking down every airport, dock, and highway to hunt down the kidnappers. As Black Mamba personally executes the corrupt perpetrators one by one, will she storm the offshore fortress in time to rescue her daughter unharmed?
