Zero Sum (2016)

Ruth (Aimee-Ffion Edwards) awakens in a barren spacecraft with no recollection of her past, sustained by a plastic tube attached to her lower back. She pulls it free, and as the intense pain fades, fragments of memory resurface. Gazing through the window, she sees countless identical vessels circling a verdant planet. She recalls the vow she made to start over, far from Earth among the stars. Then a sound echoes from behind a partition, and Ruth understands she is not by herself.
