Jack is an orphan. His parents brought him to Mars, believing it to be the realization of their dreams. When a plague claimed his mother and shattered his father, Jack was spared, but forever changed.

Alone and haunted by strange dreams of the planet's surface, Jack must find his way. The only safe haven is an orphanage for Red Children known as the Nursery, run by a woman called Nana. It's a place Jack can call home.

When a new doctor comes, looking for a cure for the plague that claimed his mother, Jack's world is turned upside down. He and the other children are treated like lab specimens. They fear for their lives.

Jack must make a choice. Work with the doctor and find a cure or fight for his way of life.
