The story follows Laura, a Spanish woman living in Buenos Aires, who returns with her teenage daughter Irene and young son Diego to her small hometown just outside Madrid for her younger sister's wedding. Laura runs into her old friend Paco in the town square while Irene flirts with a local teenage boy named Felipe. After dancing with Felipe at the wedding reception, Irene complains that she does not feel well and goes upstairs to sleep. Later that night, Laura goes to check on Irene only to find she is missing. She receives a text message from kidnappers urging the family to pay a large sum or they will kill Irene.The family decides not to involve the local police for Irene's safety, as the kidnappers will kill Irene if the police get close. Laura receives a text message demanding EUR300,000 against the release of her daughter. Chaos ensues as the family scrambles to raise the money. During a heated confrontation with Laura's father Antonio, Paco learns that some family members believe he "owes" them money, as the land Paco's vineyards were built on was sold to him by Laura at below market rate because he was the child of the family's servants. Laura's brother-in-law, Fernando, calms the situation and brings in his friend Jorge, a retired police officer, for consultation. During a private conversation, Jorge tells Laura that she should include members of her family on her suspect list, including her husband. Desperate to help, Paco considers selling his lands to a business partner so he can pay Irene's ransom but his wife Bea advises against it. She reveals that she has been receiving the same text messages as Laura on her phone.Laura's husband, Alejandro, is informed of the kidnapping and arrives in town. He receives a cold welcome by Laura's family before going with Laura, Paco, and Fernando to meet Jorge, who asks to talk to Alejandro alone. Alejandro becomes very upset when Jorge mentions that Laura discussed his past problems with alcoholism and his ongoing bankruptcy. Enraged by how a stranger knows this information, Alejandro leaves with Laura and they argue about the best course of action. Laura confesses to Paco that Irene is his biological daughter, conceived sixteen years prior during Laura's trip to her hometown shortly after she and Alejandro married. Shocked by this information, Paco readies to sell his estate, but Bea angrily refutes Laura's claim. She believes Laura is lying about Irene's paternity and might be involved in the kidnapping herself in order to get money out of Paco. He leaves the house anyway and comes back hours later with a duffel bag containing the ransom money. After examining Irene's upstairs room, Jorge tells Alejandro and Laura that whoever kidnapped Irene knew that Paco was her father. During a conversation with Fernando, Alejandro learns that the whole family, along with some of the townsfolk, know that Irene is not his biological daughter because of her resemblance to Paco.That night, Laura's niece Rocío sneaks out of the house and travels to an abandoned, run-down building on the outskirts of the town. Once there, she meets with her estranged husband Gabriel and his accomplice Luis. It is revealed that all three of them orchestrated Irene's kidnapping and that Gabriel has been sending the ransom messages to Laura. Luis admits that he is the one who has been sending the same ransom messages to Bea, unbeknownst to Gabriel. This angers Gabriel and prompts a crying Rocío to beg for her husband to let Irene go; their collective actions have deviated too far from the original plan and caused irreparable damage. Despite Luis's protests, Gabriel agrees to let Irene go at dawn. Rocío returns home and is questioned by her mother Mariana, Laura's older sister, as to her whereabouts. Rocío brushes her mother off, leaving Mariana suspicious.At dawn, Paco receives a voice recording of Irene begging for her rescue and a text message of where to perform the exchange. He grabs the duffel bag and drives to the destination. Once he arrives, Paco gets out of his car and rushes to inspect a loud noise made by something large being tossed into a nearby river. When he returns to his car, he finds Irene tied up in the backseat and the bag missing. He delivers Irene to Laura and Alejandro, who rush Irene to a hospital. Exhausted, Paco returns home, only to find that Bea has left him.Shortly afterwards, Laura and her family pack their belongings and say goodbye to the family as they will be returning to Argentina. Felipe promises to call Irene when she gets home. In the car, Irene asks Alejandro why it was Paco who rescued her. He does not answer. As the car drives off, Mariana sits by herself in the town square. She calls over her husband, Fernando, and asks him to sit down. As the two begin to converse, the screen fades to white.
