A flu epidemic at Dewey High School affords Mike (Kirk Cameron) the opportunity of becoming a substitute teacher. But it's not going to be easy sailing: Not only is Principal DeWitt (Sam Anderson) openly hostile to former troublemaker Mike, but our hero has been assigned the rowdiest class in school, crammed full of hostile kids just one step removed from the penal system! Meanwhile, baby Chrissy learns a dirty word--and refuses to stop repeating it. Watch for future ER and Men in Trees regular Abraham Benrubi as an oversized high-schooler. ~ Hal Erickson, Rovi
