Discovery+ has debuted an astonishing trailer for the Eli Roth documentary ‘Fin’ which exposes the truth behind the mass killing of Sharks.

In the doc, Roth and a professional group of scientists, researchers and activists sail around the globe to unveil the truth behind the death of millions of sharks, exposing the criminal enterprise that is impacting the extinction of the misunderstood creatures.

It features work from photographer Michael Muller and the support of organizations such as Oceana, Sea Shepherd, and Wild Aid.

Oscar® winner Leonardo DiCaprio executive produces the film along with actor, producer and shark activist Nina Dobrev and President of Lionsgate Nonfiction Television and Pilgrim CEO and Chair Craig Piligian.

In a statement Roth said, FIN is the scariest film I’ve ever made, and certainly the most dangerous, but I wanted to send a message of hope to end this needless massacre of sharks. They keep our oceans clean to produce half our oxygen, and they deserve our respect and deserve to be saved, especially now when the shark fin sales ban is going before the House. It’s an honour to be joined by Leonardo DiCaprio to bring it to discovery+ audiences, and I couldn’t have done this film without the incredible support of Lionsgate and the amazing team at Pilgrim. I wanted to show the crisis from all sides and paired with an action campaign we can make the change necessary to protect them.  Fifty years ago the world came together to save the whales, then we did it for dolphins, and recently for Orcas. It’s time to do the same for sharks, and time is running out.”
