Paulina Escobar (Sigourney Weaver) is a housewife married to a prominent lawyer, Gerardo (Stuart Wilson), in an unnamed South American country, which is implied to be Chile. One day, a storm forces Gerardo to ride home with a charming stranger, Dr. Miranda (Ben Kingsley), while the power at his home is cut. Paulina is convinced that Miranda was part of the old regime and that he tortured and raped her for weeks while she was blindfolded. She takes him captive to determine the truth. Despite attempts by both her husband and Miranda to convince her that he is innocent, Paulina is certain that he is guilty and forces her husband to act as Miranda's "attorney" in the "trial" she arranges for him. Miranda conspires with Gerardo to agree to a false confession, as Paulina states that this is all she wants in exchange for Miranda's life. They write up a false confession and present it to Paulina, but she becomes enraged and deems Miranda unrepentant, threatening to kill him. As Gerardo tries to stop her, Miranda gets hold of Paulina's gun and threatens to kill her if he is not freed. However, as he advances toward the door, the power in the house turns on, and Paulina hits him, regaining control. In a last-ditch effort to save his life, Miranda implores Gerardo to call the Spanish medical school where he claims to have been at the time of Paulina's rape. She leads him blindfolded out of the door to the edge of the cliff. Gerardo contacts the school, where Miranda's colleague seems to confirm the story. He races to inform Paulina, now convinced that Miranda is innocent. However, Paulina refuses to believe it, stating that doctors at that time created alibis to conceal their identities. Miranda finally tells them that he really was the doctor, that he enjoyed brutalizing Paulina, and that he was sorry that the old regime fell. Enraged, Gerardo attempts to throw Miranda from the cliff, only to realize he cannot bring himself to take a life. Paulina apparently accepts the confession, and they both leave Miranda on the cliff as he stares down at the water. The camera simulates someone falling off the cliff from his own point of view. In the final scene, Paulina and Gerardo are at the same concert where the film began with Miranda also present, looking down with his wife (Krystia Mova) and sons (Jonathan Vega, Rodolphe Vega). Paulina and Miranda cast uncomfortable glances at each other, and Miranda looks away. Miranda glances down at the couple again as the camera shows Gerardo glancing up towards the balcony at the now off-screen Miranda.
