By part 4 the SUBSTITUTE series is almost entirely divorced from the theatrical original. It’s the only one not written by Rocco Simonelli and Roy Frumkes – this time it’s Dan Gurskis, who apparently did an uncredited rewrite on part 3. It’s Treat Williams as Karl Thomasson again, but he’s not even really an undercover substitute. He discusses it that way, but really he’s given the job of history teacher at a military academy under slightly sneaky but not really clandestine circumstances. He’s not THE SUBSTITUTE anymore, he’s THE NEW TEACHER.
For once he’s not on a mission on behalf of a teacher – this time an old general friend is worried about his nephew at this academy, and is sending in a team to check things out. He was right to be worried because the head of the academy, Colonel Brack (Patrick Kilpatrick), is an open white supremacist maniac who’s training an elite corp of neo-nazis called “The Werewolves” and sending them on terrorist bombings of minority owned power plants (?).
