HBO has released the first trailer for its miniseries Chernobyl, and it’s predictably intense. The trailer features nigh-apocalyptic imagery–birds falling out of the air, skies filled with smoke and fire–and plenty of chilling dialogue to match.

“A just world is a sane world,” intones the opening voice-over. “There was nothing sane about Chernobyl.”

The trailer also shows off the prestigious cast, including Stellan Skarsgård as the Soviet deputy prime minister, along with two-time Oscar nominee Emily Watson, and Mad Men‘s Jared Harris as nuclear physicists.

The five-episode miniseries is a dramatization of the 1986 Chernobyl disaster, during which a massive explosion at the Chernobyl power plant in the Soviet Union released radioactive material across the country and into Western Europe. The disaster remains the deadliest and costliest nuclear power plant accident in history.

Chernobyl premieres on HBO May 6. Watch the full trailer above.
