A covert team of psychologists carry out hidden camera experiments on the public. The People Watchers manipulate people in every kind of situation; the job interview, speed dating, identity parade, supermarket, high street, bar, restaurant, school and courtroom. Through hidden camera experiments, three psychologists show viewers how people think and how it affects everything we do. They play characters in hidden camera experiments to show how the minds of unsuspecting members of the public react to a variety of situations. They draw them into scenarios to study and measure their reactions. Viewers gain an insight and understanding into how human beings think and behave.
