Ridley Scott’s “The Dog Stars,” is a riveting, epic thriller set in a world where survival is instinct, but humanity is a choice. Scott tells the story of Hig, a young pilot who, together with a military survivalist, Bangley, has carved out an efficient but isolated homestead in a brutal post-apocalyptic world until a mysterious radio transmission spurs Hig to venture into the unknown in search of the hope and humanity he still believes exists.
