In just one day, a whole world can be transformed, and the effects can still be felt to this day. An act of terror can bring neighbours to the edge of war; a religious cult can attempt to poison thousands on a subway, and a natural disaster can contaminate the soil, earth and air for generations.

In this series, we travel to Fukushima, where some 10 years after a nuclear reactor goes into meltdown, the government is trying to do the unprecedented - decontaminate and repopulate whole towns in the area.

We investigate how the two Koreas’ game of brinkmanship in the 1980s resulted in a plane crash that reverberates to this day.

We explore how a terrifying poison gas attack on the Tokyo subway system exposes years of official failure to prevent a new religion mutating into a murderous cult.

And in Indonesia, we look at how an unprecedented natural disaster all but destroys a society but also triggers an end to a bitter civil war.

Through eyewitness testimony and dramatic newsreel footage, this series gives unprecedented insight into some of the biggest recent events in Asia.
