 Professional mercenary Karl Thomasson arrives in Brooklyn to attend the funeral of his brother Randall, who was murdered while trying to stop a carjacking that has been blamed on the "Brotherhood", a vicious street gang led by "Little B" (played by Guru). Karl, who believes there is something more to it, goes undercover as Randall s replacement at Lenthrop High School in Brooklyn, where Randall was a history teacher, so Karl can investigate the Brotherhood. Karl becomes the protector of Randall s daughter Anya when their lives are threatened by whoever is behind the recent string of carjackings, and the plot behind the carjackings runs a lot deeper than the Brotherhood, and the threat is a lot closer to Karl and Anya than they dare to think.
