PAX (1994)

Franny (Amanda Plummer), an absent-minded American girl, is in Lisbon to deliver an important package. Unfortunately she has lost the address and only knows that the recipient's name is João. When she meets an old prostitute, Esmeralda, the two join forces and begin cruising the town at night, across the streets and the local bars, meeting Lisbon's unconventional night fauna, to try to find João.
