A film directed by Ivan Reitman. Released in 1990.
Arnold Schwarzenegger stars as detective John Kimble, a man who has been chasing a drug dealer named Cullen Crisp. When he finally tracks Crisp down, he learns that the only way he can put Crisp away is by having his ex-wife testify against him. Kimble finds out the name of the school Crisp's son attends. He is then assigned a new partner, Phoebe O'Hara, who is going to go undercover as a kindergarten teacher, and the two travel to Astoria, Oregon. Unfortunately for Kimble, O'Hara becomes ill, and the only person who can take her place is him.
