Hybrids, outcasts, of their own world. Five children, Josh, Bailey, Ella, Eric and Blaire, live on planet Mellania. They each have one human parent and one Mellanian. Their partial alien DNA means they possess unique powers, making them both an asset and a threat to the Mellanian government. Captain Melsom, Mellania's ruler, works beside Lucia, a malicious demon, to eliminate the young hybrids.
The operation involves transferring the children to Earth where they will be immediately killed. Lucia is to be transported with them to oversee their termination. Upon arrival, things don't work out quite as expected.
The children have to draw on their powers to survive now, all the time trying to find Lucia before she can wreak her own chaos upon Earth.
But just who is controlling the situation and for what reason suddenly becomes very clouded. Even those closest to them begin to drift apart, and it becomes increasingly clear that nothing is what it seems.
