Simon Newton (James McAvoy) is a senior staff member of Delancy's auction house. He is particularly good at protecting famous paintings when they are stolen. On this day, a painting by the famous painter Goya, "Witches In The Air", is being auctioned, and the painting is expected to be worth 25 million pounds. At the same time, a group of thieves led by Franck (Vincent Cassel) is planning to steal the painting. Franck's plan went very smoothly, and Simon was also familiar with this scene. He quickly packed the painting in a bag and moved it. When Simon was about to send the painting to a safe place, Franck appeared, shot Simon in the head with a gun, and took the painting away. Simon fainted. Franck returned home and was surprised to find that he opened the bag, but found nothing inside. After Simon woke up, Franck found him.

So Franck took Simon to find a female hypnotist, Elisabeth (Rosario Dawson), hoping to restore his memory through hypnosis...
