Set in the year 2524, where the galaxy is separated into three main colonies (Earth, Zafdie and Ellora), Cosmic Sins starts when a colonist makes first contact with a new alien civilization. Fearing the worst after the aliens make their way back to Earth as stowaways, a ragtag team of soldiers – including disgraced soldier James Ford (Bruce Willis) – go to the planet Ellora to stop an interstellar war before it starts.
