The Great Hack tells the story of how consulting firm Cambridge Analytica used Facebook data to influence critical elections, and how such uses of technology threaten our democracy.

By now, many of us know that the devices and websites we use are collecting our data. But what are they using it for?

What if your data is not only being used to sell you personalized goods and services, but to reshape your reality?

Filmmakers Jehane Noujaim and Karim Amer previously collaborated on The Square, a documentary about the Egyptian Revolution in which a social media-driven mass movement brought down an authoritarian president.

Now they turn their lens to the darker side of social media, examining how it can manipulate people as easily as it can liberate them.

Interviews and exclusive footage take us behind the scenes of the 2018 Cambridge Analytica scandal, the company's misuse of private user data from Facebook, and its role in the Brexit referendum and the Donald Trump presidential campaign.

The Great Hack casts a chilling spotlight on the forces that are being used to manipulate our psychology and our society.
