In each episode, the members of the "Questions" club — Astra, Zhenya the hedgehog, Jan the bluebird and Bonya the snow troll — receive a video question from young viewers, and from that moment their adventures in search of an answer begin. Having expressed a number of ridiculous hypotheses, the characters test them experimentally, going on an incredible journey through space or time: to different countries, to the past and the future, to digital space, into space or underground. And in the end, they always get to the truth and record a video response to an inquisitive viewer's question.
