From the World of John Wick: Ballerina

After a veritable bloodbath, the Macarro family is practically wiped out. Only Eve (Ana de Armas) is still alive - and she swears revenge at all costs. With this plan in mind, she seeks help from the Ruska-Roma family, first to train as a cold-blooded killer and then to set out in search of those who have killed her own family. But Ruska-Roma life under the strict rule of the principal (Anjelica Huston) is anything but a bed of roses and the road to revenge is long and rocky.
