Sky People/Delinquents

The  are a group of teenagers younger than 18 who were arrested for committing various crimes. As all crimes in the Ark are capitol crimes, criminals are put to death immediately. However, those under the age of 18 are instead sent to lock-up to wait until they reach the age of 18, when they will also be put to death. The delinquents were sent to Earth to see if it was yet inhabitable for humans since the ark is dying. They were promised that their crimes would be erased, but the truth behind this has yet to be seen.
