Teetering on the edge of the Redshift Quasar, the last human colony has been destroyed leaving only the colony’s children behind and now every teenager’s dream is their worst nightmare.

Is it some kind of coming of age in space? Lord of the flies in space?
Or is it some kind of psychological horror movie?
Something dArk and nasty is now lurking on the colony that the children must fight?
Who is the threat: themselves, fear or a real physical threat?

No idea what your film is about.

It starts with the adults in a frontier colony being wiped out. Then what happens?

When I think of Children, I don't think teenagers. Have they been trained to survive on their own or do they have to figure it out? Does their dream of freedom from parental authority turn into a nightmare against an opponent? Themselves? The latter, I'm thinking Lord of the flies in space.
