Plot

Captain Karl Thomasson, an ex-Special Forces soldier and retired mercenary, is approached by his old army buddy Teague who gives him a mission: working undercover at a military school where Ted, Teague's nephew, is one of the cadets. Teague believes that the cadets and the student faculty are part of a group of white supremacist neo nazis called the Werewolf Unit. Officially, the werewolves are a special unit being run at the school. Karl accepts the mission and begins working as a history teacher at the school, seeking to expose and eradicate the unit. While investigating, Karl teams up with Devlin, a martial arts teacher at the school who served with Karl in the U.S. Army. They learn that Colonel J.C. Brack is leader of the unit and Ted is one of the cult members.

Reception

Robert Pardi of TV Guide rated it 2/4 stars and wrote that the film, though preposterous, is tolerable if one lowers their expectations. Aaron Beirle of DVD Talk rated it 0.5/5 stars and wrote, "Even for the low-budget action (or, as I call it 'cable action') genre, Substitute 4 remains a pretty dull actioner."
