De-Extinct (2017)

After being captured by extraterrestrial invaders, siblings Felicity and Archibald Walker wake in a cold cell, surrounded by concrete walls within an unfamiliar installation. In this second chapter of the mystery sci-fi Extinct series, De-Extinct continues to follow these two unfortunate siblings on the journey to find their father and the reason why they aren't affected by the aliens' gas. When the supposedly deceased President reveals himself to be alive and the leader of the organisation actually fighting the aliens, Felicity grows eager to find out why it was imperative that her and Archibald were kept alive. The discovery of their father within the installation reveals that there is more to the story than the President has led them to believe.
