Hard-edged cop John Kimble gets more than he bargained for when he goes undercover as a kindergarten teacher to get the goods on a brutal drug lord while at the same time protecting the man's young son. Pitted against a class of boisterous moppets whose antics try his patience and test his mettle, Kimble may have met his match … in more ways than one.

Jimmie Rainwood was minding his own business when two corrupt police officers (getting an address wrong) burst into his house, expecting to find a major drug dealer. Rainwood is shot, and the officers frame him as a drug dealer. Rainwood is convicted of drug dealing, based on the perjured evidence of a police informant. Thrown into a seedy jail, fighting to prove his innocence is diffucult when he has to deal with the realities of prison life, where everyone claims they were framed.
