In a lake high in the mountains of New Zealand hunter Gibbie Gibson discovers a plane wreck from WW2. When he tells it around, a gang of crooks follows and threatens him and his daughter, because they know there are 50 million dollars in the wreck. Helicopter pilot Barney helps Gibbie against them, risking his life thereby.

From the sight of a police officer this movie depicts the life in New York's infamous South Bronx. In the center is "Fort Apache", as the officers call their police station, which really seems like an outpost in enemy's country. The story follows officer Murphy, who seems to be a tough cynic, but in truth he's a moralist with a sense for justice.
