In a historical moment on November 23, 1957, the Federal Republic of Zirnitra achieved a groundbreaking feat by launching the first live creature, a dog, into outer space. This event ignited a fierce space race with their rival, the United Kingdom of Arnack, as both nations set their sights on eventually sending humans beyond Earth's bounds. To understand the potential hazards of space travel on the human body, Zirnitra proposes a daring solution: using vampires as test subjects due to their striking biological resemblance to humans. Irina Luminesk, a vampire taken from her mountain abode, surprisingly agrees to participate in this risky experiment without resistance, sparking a unique journey. Lev Leps, once a leading contender for the title of the inaugural human cosmonaut, is tasked with accompanying and guiding Irina on this uncharted venture. As they delve into the mysteries of space together, Irina and Lev find themselves drawn not only to the cosmos but also to each other, forging a bond that transcends the boundaries of their origins.
