Following the theft of his phone, the Dutch director Anthony Van Der Meer had the idea to make a film with the complicity of a new trafficked phone that he will be flying in the subway of Amsterdam. Thanks to spyware, he will be able to track down the thief and recover a lot of data on him (videos, sounds, photos and locations), allowing him to learn a lot about this famous thief. Some empathy will even invade the victim. A question then arises from his experience: Can we really know a person when we rely solely on the information retrieved from their phone?
