Earth. At the moment, it is a planet that can only be seen from space, all inhabitants killed off in a foolish nuclear war between one another, leaving the planet soaked in deadly radiation. Only twelve space stations, orbiting the planet remain. As time went on, the space stations chose to band together and attach, forming the Ark, the only place humans could survive. More than 100 prisoners on the ship under the age of 18, convicted of multiple crimes, wait, knowing that their time is running short, for when they turn 18, they will be ejected into space, in an activity known as being "floated." Time is running out on the Ark, rations running short, and oxygen becoming scarce. The only hope is in 100 teenage prisoners who will be sent down to earth in a secret mission to find out if the earth is habitable again. When humans thought that making it to the moon was the biggest achievement, now we're trying to get back to Earth.
