Inside the worst nuclear disaster of the century, one year later this FRONTLINE special interviews the men who risked their lives to save the Fukushima Daiichi nuclear plant as they reveal what really happened when it was hit by a tsunami caused by a devastating earthquake on March 11, 2011.

In the desperate hours and days after the Fukushima nuclear disaster, the fate of thousands of Japanese citizens fell into the hands of a small corps of engineers, firemen, and soldiers who risked their lives to prevent the Daiichi nuclear complex from a complete meltdown.

FRONTLINE tells the story of the workers struggling frantically to reconnect power inside the plant’s pitch-dark and highly radioactive reactor buildings; the nuclear experts and officials in the prime minister’s office fighting to get information as the crisis spiraled out of control; and the plant manager who disobeyed his executives’ orders when he thought it would save the lives of his workers.
