From the World of John Wick: Ballerina pointes the movie franchise in a new direction while celebrating the past. This story takes place between John Wick: Chapter 3 and Chapter 4 in the chronology of the multiple films.
Eve Macarro is the young orphaned daughter of two assassins and is saved by Winston Scott to be raised in New York. She balances a life of dance with training to be a Kikimora assassin. This leads her to adventures in Prague and Austria to battle it out with dark forces.
Ballerina tries to go deep with Slavic mythology and one ominous character talks about the Kikimora spirit, which exists in the shadows and seeks revenge. It's all smoke and mirrors, though and the tale is devised to inspire Eve into violence.
