[00:00:00]On August 21st, 1986, an entire village went to sleep and never woke up. In the remote hills of Cameroon, Lake Nyos looked perfectly normal that evening.

[00:00:09]Families finished dinner, children played outside, everyone prepared for bed. By morning, 1,700 people were dead.

[00:00:17]When rescue teams arrived, they found something that defied explanation.

[00:00:21]Bodies lying peacefully in their beds, children still clutching toys, families gathered around dinner tables. No wounds, no signs of violence, no struggle. Even stranger, 3,500 livestock lay scattered across the countryside, all dead. What killed an entire region in a single night? Scientists discovered that Lake Nyos had become a massive death trap. Carbon dioxide had been building up at the bottom for decades.

[00:00:47]That night, it all erupted at once. An invisible cloud of poison gas rolled silently through the valleys. It displaced all the oxygen. People simply suffocated where they stood. The terrifying truth? There are similar lakes around the world, time bombs waiting to explode, and we have no way to predict when they'll strike next.
