Roza Plevitskaya is an Air Force Lieutenant and the only female cosmonaut candidate. She is a former ace pilot who was known as the "White Rose of Sungrad".

Set in a fictional world, 10 years after a long war divided the world into two superpowers: the Union of Zirnitra Republics in the east, and the United Kingdom of Arnak in the west. Both of these superpowers now test their ambitions against each other in a space race. In 1960, the Union's Premier Gergiev announces the Mechtat Program, a prestigious plan to launch manned missions into the final frontier. To this end, the Republic establishes the isolated city of Laika 44, where cosmonaut candidates compete for planned manned missions to space, and scientists develop the technology to make it happen, all in an environment of secrecy.
 
The story centers on Lev Leps, a backup astronaut candidate, and his new companion, the vampire Irina Ruminescu. As part of a daring new Operation Nosferatu, the Mechtat Program will use Irina as a test subject for various conditions expected in space, and ultimately as part of a manned mission, with Lev overseeing Irina's training as a cosmonaut. For reasons of their own, both dream of going into space.

In an alternate version of the 1960s, two global superpowers have emerged after a savage war: the Zirnitra Union and the United Kingdom of Arnack. East and West are locked in a fierce race to send the first crewed flight into outer space, leading the Union to develop a secret agenda: the Nosferatu Project, which aims to use vampires as spaceflight test subjects. Similar to humans but feared and reviled, vampires are assumed to make the perfect "guinea pigs" for such a dangerous task. Lev Leps, a Union soldier and aspiring cosmonaut, is tasked with overseeing vampire Irina Luminesk aka N44, who has been chosen for the operation–and he can't quite detach his feelings from the vampire girl as planned. Faced with pressure and peril, will either of them manage to fly into the cosmos?
