In the near future, a desperate mission to save humanity unfolds aboard the starship Somnus, carrying the last remnants of mankind in cryogenic sleep. Led by the determined Captain Meryl Griffiths and her conflicted first officer Marcus McMahon, the crew awakens to a silent ship and a terrifying reality—their carefully plotted course has gone horrifically awry. As they navigate the claustrophobic corridors and confront malfunctioning systems, paranoia begins to fracture the team, including the pragmatic engineer Mac McDonald and the resourceful specialist Jennifer Moylan-Taylor. This tense sci-fi thriller from director Chris Reading masterfully blends adventure with psychological dread, trapping its characters in an inescapable void where the greatest threat may not lurk among the stars, but within the ship's own haunting silence and the fragile minds of those trying to survive it.
