In this sequel of the popular film in 2014, legendary professional killer John Wick (Keanu Reeves) is forced to give up retirement ideas by his former associate, who plans to take control of a dark internationally-assassinated assassination organization. Bound by a blood covenant to help him, John travels to Rome where he faces some of the most deadly assassins on the planet.
After triggering a real slaughter against the murderers who killed his dog, the retired John Wick retired killer recovers his boyfriend Mustang 1969 from the Russian mobsters who had stolen it, the consequence being a spectacular pursuit of cars on the crowded streets of New York. Shortly after returning home, John’s plan to resume his quiet civilian life is overwhelmed by the Italian gangster Santino D
‘Antonio (Riccardo Scamarcio), who presents himself at his door with a gold’ mark ‘, forcing him to pay his old debts. Taking into account Winston’s recommendation (Ian McShane), the pivot of The Continental Assassin Secret Society, who reiterates that he must respect the organization’s ancient code, John accepts the burden Santino entrusted with: to liquidate his own sister, Gianna (Claudia Gerini), the unmistakable leader of the Italian Camorra crime syndicate.
Arriving in Rome, John stays at Il Continentale, arming herself up to her teeth, and passing the harsh security measures imposed by the Camorra Mafia to liquidate Gianna in her bedroom. Leaving behind dozens of deaths, John escapes from Rome, but with two well-trained assassins of Camorra, Cassian (Common) and Ares (Ruby Rose).
Back in New York and left without a roof above his head (Santino destroys his house), John seeks help from the mysterious Bowery King (Laurence Fishburne) and his shadow army. Thus, using Brazilian jiu-jitsu techniques, Glock pistols and even pencils, John takes revenge on those who have mistaken them. In the midst of slaughter, John finds the inner strength he needs to face the assassins’ code – but can he save his own humanity?
