Running From Change

Crystal Kunz, an astronaut, is on board the International Space Station when it is struck by a micro meteorite, causing minor damage to the outside of the hull. When found, it is brought inside the station, and everyone on board the station holds it and takes a look at it. However, what they don't know is that it has a dormant strain of a gene-changing virus from space that infects everyone. When the first of them begins to get sick, they all think it's a normal cold, but as it gets worse and others get sick, with the same symptoms, NASA begins to worry and emergency lands everyone on board and puts them in quarantine. All the while, the virus is changing their genetic makeup. Crystal soon starts growing wings on her back throughout the sickness, along with Vincent Vuhad, another astronaut who was on board.

When close to death and given a tentative cure, Crystal and Vincent begin to recover from the sickness as their wings continue to grow. As they gather their strength back, the other four astronauts are given a new cure to cure the genetic changes and the sickness, but instead it does the opposite, making their sicknesses worse and killing them. Crystal and Vincent can't do much about them, but instead they throw themselves in learning how to fly with their new wings.

By the time they've gotten pretty good at flying, aliens attack Earth and kill every single human being on the planet.

Except them.

Join Crystal and Vincent as they run from aliens and go cross-country while trying not to die!
