PBS' FRONTLINE cringe-inducing documentary, Japan's Nuclear Meltdown, takes you about as far inside Fukushima's rupturing, quake-paralyzed nuclear plant as you want to get. We've pulled together the most jarring moments here, where Japanese workers struggled to prevent a disaster from exploding further.

Exploding, literally. As you'll see, rescue workers and engineers were working inside a building that was literally self-destructing. The moment they describe, post-blast, nuclear materials seeping into their masks, and visions of certain death, the meltdown loosens itself from year-old headlines and feels new again. It feels real again—and for the people of Japan, it is. Be sure to watch the doc in its entirety—it's a terrific film.
