Set in the distant future, 97 years after a nuclear apocalypse has devastated the surface of the Earth, the only survivors are the approximately 2,400 inhabitants of 12 national space stations that were in orbit at the time of the apocalypse, which have come together in a massive station Scene from The 100 television seriesknown as the Ark.
Three generations have survived in space. The Ark has strict measures, including population control and capital punishment for citizens over 18 years of age. Eventually, life support on the Ark begins to fail. For the first time in nearly a century, there is talk of returning to Earth.
For the 100, Earth is an alien planet. The 100 quickly discover Earth can be magical one moment and lethal the next. With the survival of the human race entirely in their hands, the 100 must find a way to transcend their differences, unite, and forge a new path on a radically changed Earth that is primitive, intense and teeming with the unknown.
