This undemanding picture proves that Arnold Schwarzenegger can do comedy, providing he doesn't try too hard. As the cop forced to teach toddlers while searching for a crook's missing son, Arnie is at his best jousting with the little tykes (surprisingly few of whom have gone on to become major child stars). The romance with Penelope Ann Miller is less convincing, but not over-intrusive. Richard Tyson and Carroll Baker make almost pantomime baddies, but this isn't really a children's film and parents should keep the channel-changer handy for the more violent bits.

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.
