A school detention class is thrown into chaos when a teacher is killed and the pupils run riot - unaware that a deadly therocephalian is stalking the corridors looking for its next meal. ARC's attempts to capture the creature are hampered when youngsters hack into the automatic locking system, but the school lab proves invaluable when an even greater threat emerges. Elsewhere, Abby's menagerie is under threat. Hannah Spearritt and Andrew-Lee Potts star.
