Many people have a strong sense that their views are right and couldn’t possibly be wrong. So how do we come to hold an unshakable conviction and why is it hard to consider that we could be mistaken?

Through the eyes of a group of people who become convinced of a date for the end of the world, the film explores how people believe, how we turn beliefs into certainties, and mistake them for the truth.

A stock trader with a young family, a philosophy student about to graduate, and a retail manager who became so convinced she quit her job of 18 years. As they face the consequences of their conviction, neuroscience and psychology offer insight into how we can become convinced we’re right, even when we’re wrong.
