From The World of John Wick: Ballerina

Taking place during the events of John Wick: Chapter 3– Parabellum, the film follows Eve Macarro (Ana de Armas) who is beginning her training in the assassin traditions of the Ruska Roma. As the story opens, young Eve’s father is murdered. She is orphaned and sent to the Ruska Roma, a shadowy institution that uses its rigorous training in ballet to mask its true curriculum: contract killing. Years later, the now adult Eve rejects academy head The Director’s insistence that she refrain from seeking revenge for her father’s murder. Eve travels to The Continental in New York seeking help from Winston and Charon to uncover information about her family. As she digs deeper into the mystery of her past, Eve finds herself near a remote Austrian mountain village, Hallstatt, which is populated entirely by professional assassins — all of whom are targeting her. Eve has no choice but to fight her way out, using what she has been taught by the masters at Ruska Roma.
