Plot
Adrián, a young orchestra conductor is viewing a recorded video of his girlfriend Belén informing him of leaving him. Adrián becomes distraught. While drinking away his sorrows at a bar, he meets Fabiana (Martina Garcia) and they develop a relationship. Fabiana moves into the house that Adrián was sharing with Belén. Strange things begin to occur in the bathroom, with Fabiana observing strange noises coming from the sink and bathtub, and being scalded by an abruptly hot shower.
Adrián becomes a suspect in the disappearance of Belén; however, the investigators can find no evidence of Adrián's involvement in Belén's disappearance. One of the police investigators, apparently a former boyfriend of Fabiana, warns Adrián that if anything happens to Fabiana he will kill Adrián.
The house belongs to Emma, a German woman, who reveals a soundproof secret room intended for her former Nazi officer husband. Belén, driven by jealousy over Adrián's connection with violinist Verónica, follows Emma's suggestion to pretend she's leaving him. She records a breakup video and hides in the secret room, equipped with one-way mirrors to spy on Adrián's reaction. Belén plans to end the ruse, but loses the key, trapping herself without a way to contact Adrián.
