The year is 2185. Huge ark ships set off for the Andromeda galaxy with the task of exploring and colonizing new worlds. Soon they will be followed by the huge space station Nexus, on board of which are representatives of the five races of the Milky Way: humans, salarians, turians, asari and krogans. They will all spend six hundred years in stasis and wake up in another galaxy to start life with a clean slate, leaving behind feuds and prejudices. The last to fall asleep is Sloan Kelly, the director of the security service. Like all her companions, she is absolutely confident of success - the mission, which was prepared by the best minds of explored space, cannot end in disaster. For the first time in Russian!
