When a woman and her newborn are placed into quarantine, feared they are infected by the darkness which has devastated their homeworld. She escapes and gains the support of followers to free her twisted child from the prime evil which is bent on possessing their entire species.

Yes the story is a total mind F#$@. Think I will stick with the last one for now. Thanks guys!

Sounds still very complex to me - and complexity I feel is coming from the lack of clarity on the story. There seems to be just too much story forced into the logline.

Or perhaps this version that a former mentor just had a go at:

Set in the future, a mother escapes an alien test facility, rallies the pockets of surviving tribes to find the only one able to save what is left of the planet is her daughter.

Thanks VBK ;-)
