Capsuleman Simeon, the “brain” controlling the space station SSS-900, does not want to accept Channa Hap as a new “body” partner (according to the dossier materials, a young, ambitious person with a strong character) and does everything for this depending on him. However, when a businesslike, charming, educated and damn attractive woman comes on board the station, he, willy-nilly, has to reconsider his attitude towards her. And just in time, because literally a few weeks after the personnel changes, SSS-900 finds itself drawn into a round dance of incredible tragic events, when its inhabitants have no time for personal squabbles, when everyone’s life begins to depend on the actions of a neighbor and colleague, and the hope for victory will not die, only if everyone's hands support it. Together.
