Spain, 1950s. Montse's agoraphobia keeps her locked in a sinister apartment in Madrid and her only link to reality is the little sister she lost her youth raising. But one day, a reckless young neighbor, Carlos, falls down the stairwell and drags himself to their door. Someone has entered the shrew's nest... perhaps he'll never leave.
This is a standout of Spanish cinema: a successful psychological thriller that meticulously builds its tension. The awe-inspiring performance by Macarena Gómez, who completely loses herself in the role of Montse, is at the heart of its power.
