This is based on the life story of Frank Abagnale, who is one of the most infamous social engineers. He started his journey while he was a teenager. Abagnale ran away from home and managed to pose as a Pan Am pilot and scam thousands of miles of free flights around the world, making people believe that he was a real pilot.
This was not all. Abagnale also pretended to be a doctor and a teacher before he was caught by the FBI (years later). The movie is a good example of how social engineering is the art of human hacking, and how vulnerable we humans are.
