Geologist Vika and geophysicist Andrey are former lovers, whose emotional wound from the breakup is still fresh. They are called to a meteorite impact site in a remote forest, and feelings flare up with renewed vigor. But the characters cannot be together — a deep sense of guilt does not allow them to be happy. After all, because of their affair, as they believe, Vika's husband died, and Andrei's wife left home with a small child.
