SUBSTITUTES is something of a stock filler episode of MARTIAL LAW in which Sammo and Arsenio Hall go undercover in an elementary school in their hunt for a Colombian drug lord, whose kid attends class there. This is an all-out comedy with lots of over the top, supposedly humorous moments. The fight scenes are few and far between, and the most notable one has Louis Mandylor fighting a thug in a car park. The rest sees Arsenio Hall mugging uncontrollably and Sammo going through the motions.
