On an ordinary humid day in October, advertising director Charles (Clive Owen) missed his train, but on the next train, he met financial investment consultant Lucinda (Jennifer Aniston) because of a ticket, and the two left a good impression on each other. At that time, Charles' daughter suffered from diabetes, so he had to devote more energy to taking care of his daughter. At the same time, he suffered a setback in his career. His wife was busy with work and had no time to give him more emotional comfort. In the days that followed, Charles and Lucinda often met, and the two people with their own families became closer and closer. Finally, after a date, they came to the hotel, but this solitude was soon broken. A stranger named Laroc (Vincent Cassel) broke into the door, threatened them with a gun, robbed and raped Lucinda. The two who were worried about the exposure of their private affairs could not rely on the law, and Laroc's blackmail became more and more frequent. Charles decided to use his own strength to solve this crisis.
