Directed by the husband-and-wife filmmaking team, Zach Melnick and Yvonne Drebert, the immersive film uses cutting-edge underwater drones to explore how quadrillions of tiny invasive mussels, known as quaggas, are re-engineering the ecosystem of the Great Lakes at a scale not seen since the glaciers. To capture this epic change, the pair spent more than 150 days filming underwater, likely making it the most ambitious underwater film ever made about the Great Lakes. Part scientific exploration, part natural history adventure - the film showcases freshwater wildlife and environments like never before.
