Follows a female surgeon who has to perform an operation on a cosmonaut too ill to return to Earth immediately.

Cosmonaut Oleg Bogdanov gets severely injured during EVA at ISS. There is no way he can be brought back in his current state and he is slowly dying. The female thoracic surgeon, Eugenia Belyaeva, is selected from several specialist to fly to space and try to save Bogdanov. She is a very professional surgeon, but not very happy person in normal life: single mom with a teenager daughter, who still cannot forget the death of her husband and believes that she was the reason of it. The success of a surgery at ISS is not guaranteed to say the least, and this medium complexity surgery, if done on Earth, can easily turn into complete disaster in space.—Alexander Korotkevich
