“Haulout,” directed by the sister-and-brother filmmaking team Evgenia Arbugaeva and Maxim Arbugaev, follows a marine biologist living in the Siberian Arctic as he chronicles the planet’s largest walrus haulout.
The gathering of thousands of these marine mammals is a consequence of climate change; warming seas have forced the walruses to congregate on land, where stampedes and trampling can result in fatalities.
