In one town lived a student named Student, and a cannibal named Cannibal Cannibalovich. By day, as expected, the student studied, and at night he flew across the sky and grazed stars. And the cannibal had four daughters: three—just like daughters, but the youngest, Ninochka, terribly upset her father—she absolutely didn’t want to live like a cannibal. And one day, Ninochka met the Student.
