The Substitute: Failure Is Not an Option

Captain Karl Thomasson (Williams), 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 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 (Patrick Kilpatrick) is leader of the unit and Ted is one of the cult members. During his investigation, Karl befriends and falls for Dr. Jenny Chamberlain (Angie Everhart) who believes that the Werewolf Unit is just another elite group and is unaware of their clandestine assignments. One night he gets ambushed by two enemy students possibly sent by Brack. Karl dispatches his would be assailants and survives the night. Karl and Devlin discover information of a recent mission the Werewolf Unit were a part of in disrupting Minority operated businesses in order to cause racial chaos around town. Karl tries to warn and appease Teague that the Werewolf Unit are not what Teague believes it to be. The Werewolf Unit are later assigned to take on what Teague believes to be a training exercise which in reality is a terrorist action to destroy and bomb a power plant facility that powers a section of the town's minority-controlled businesses and housing. The mission runs smoothly as Teague has second thoughts and, in the process, loses one of the cadets as he falls to his death. With Lim leading the assault, they evacuate as the bombs detonate. Brack enlists the help of a renegade North Korean operative named Lim (Simon Rhee) to help get rid of Karl and his allies to silence them from ascertaining the truth of the secret operations the Werewolf Unit conduct. Around this time Karl and Jenny discovers a romantic relationship which causes more friction with Brack. == Cast ==

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." == References ==
