Skulltimate Roller Maze (SKRM) is a very popular tournament of roller derby among dangerous obstacles. When the girls from Monster High claim that they want to participate in this year’s SKRM, the guys claim that this is a sport only for men. The girls disagree and they decide to train really hard and to compete on the SKRM to prove a point. They get their chance to enter the Monster High team when some of the boys get injured during a race. In Friday Night Frights, and despite its scepticism, the boys have to admit that the girls are ready to compete on the SKRM against the always rivals of the school: Granite City High.
