People like Pam and Jerry North enjoy living in New York because there's always something going on - at any hour of the day or night. But if there's one time when the big city sleeps, or even dozes off for a moment, it's in the wee hour just before dawn, when the streets are deserted, and Pam and Jerry's car has just broken down on the outskirts of town... Cue murder, mayhem, a missing ring - and a milkman!
