The world is at war with something unknown and the survivors must work together to prevent the Earth from vanishing.
Although it's only coming in 2010, a trailer for "Day One" has been out there. It is a leak which writer Jesse Alexander explained on Twitter as "NBC's upfront ad event". The showrunner wrote, "VFX not complete. Temp music. But it's a first look at my show!"
What begins as an ordinary day suddenly turns into chaos when a global disaster strikes the high buildings. The show, which is expected to be part of NBC's midseason show, is deemed as "War of the Worlds" meets "Lost". It will follow a group of people who have survived a post apocalyptic event and must work together to rebuild and save the Earth from a menace that have consumed countless other worlds.
The global catastrophe is taken from the perspective of southern California residents living in an apartment complex. Due to the mysterious event, the communication line has been shattered and the shape of the world has changed, literally.
13 episodes are in order and producers are looking forward to replace "Heroes" with this show.
