'A report comes in of a train derailment near Circular Quay. Smoke billows from the wreckage and victims pour onto the streets. As the emergency workers arrive at the chaotic scene, they realize the biggest threat is only just emerging. People without a scratch are collapsing on the ground and dying - and it is spreading. Unless someone can work out what is going on the death toll will continue to rise.

'This moment is "Event Zero."

'Event Zero is a web series from the team that brought you the award-winning hit internet movie "The Tunnel", seen by over 3 million people worldwide. Event Zero tells seven interconnected stories of people caught up in an event much bigger than they are, as they struggle to piece together why people are dying, and what has happened from the moment of derailment. Each episode will re-tell the incident from a new character's perspective until finally in episode 7, the sinister secret behind "Event Zero" is revealed.'
