The longest of the stories is also called "Half a Life" and tells the story of a Russian woman kidnapped by an alien spacecraft in the years following the second world war. In a distant, but unspecified future, human cosmonauts discover the alien ship floating in space, a derelict. Entering the ship, they soon realize that it was automated - run by robots with the apparent mission of collecting biologic specimens from different planets. (The purpose of this exploration remains undetermined, but one of the humans speculate that it may have been a lucky break for mankind that the ship never returned home.) Exploring the ship, one of the cosmonauts finds bits of a journal written in Russian from the ship's sole human occupant. They learn of her attempts to bond with the ship's other intelligent specimens, of their plot to escape and to outwit the ship's crew of automatons. When the cosmonauts find the journal incomplete, they are forced to discover for themselves the fate of the author.
In "I was the first to find you," the crew of the Earth ship Spartak have spent years on a deep space expedition.

In "May I Please Speak to Nina," the narrator has been trying to reach his girlfriend Nina by phone. Instead, he keeps reaching another Nina, one who thinks that she's in the 1940s, as the Soviet Union is besieged by war. For the narrator, it's the 1970s. Perhaps the girl is playing a trick, or is actually a demented old woman for whom time has lost its meaning. The narrator, with his own bitter memories of that time, cannot discard the possibility that his phone has somehow crossed wires through time.
