Quarto do Pânico (1970)

Trapped in their brownstone's panic room, a hidden chamber built as a sanctuary in the event of break-ins, a newly divorced woman and her young daughter play a deadly game of cat-and-mouse with three intruders during a brutal home invasion. But the room itself is the focal point because what the intruders really want is inside it. A Portuguese language remake of David Fincher's 2002 thriller.
