An escapee from juvenile detention murders a taxi driver and a few drug dealers and becomes a big threat once he hides in a public schools, putting in danger hundreds of lives. Temple disguises as a student to catch the killer, in an operation that almost cost Ella the guard of her nephew, if it wasn't for Mannion's interference to the judge.
