Humanity is about to learn that we’re not alone in this mysterious sci-fi thriller. When astronaut Sam Walker returns from her first space mission, she’s found miraculously alive in a punctured capsule floating deep off the coast of the Atlantic Ocean. Required to be quarantined, her adopted father General William Harris places Sam under NASA surveillance in a high security house, isolated in the woods. Reunited with her husband, Sam appears to be re acclimating and preparing for her next mission. However, when disturbing occurrences begin happening around the property, she fears that something extraterrestrial has followed her back to Earth, and that the agencies meant to protect her are endangering her life. Not even those close to her can be trusted.
