AN UNFORGETTABLE NIGHT is a TV movie that blends film noir and comedy genres. The story begins with three longtime friends in their thirties, Tó (André Gago), Alberto (Alberto Faria), and Paulo (Lourenço Henriques), who, after a lively dinner, decide to follow Tó's suggestion—a married medical sales representative—and go to a nightclub in Spain near the border with Portugal. Alberto suffers a heart attack. The nightclub owners prevent them from calling an ambulance, and the friends leave with Alberto's lifeless body in the car's trunk. Still in Spain, they stop at a gas station, and the car gets stolen.
