War is coming to the world of "John Wick."

Star Keanu Reeves confirmed the title of the third movie in his assassin franchise, telling ComingSoon.net that it would be called "John Wick 3: Parabellum."

That's been the project's working title, but what does it mean?

"Prepare for war," Reeves explained.  "It’s part of that famous sentence, ‘Si vis pacem, para bellum,’ which translates as, ‘If you want peace, prepare for war.'"

That war is brewing is no surprise given how "John Wick: Chapter Two ended." A host of assassins will be coming after him now that there's a bounty on his head for killing a member of The High Table at the Hotel Continental.

The official synopsis reads: John should have already been executed, except the Continental’s manager, Winston, has given him a one-hour grace period before he’s 'Excommunicado' – membership revoked, banned from all services and cut off from other members. John uses the service industry to stay alive as he fights and kills his way out of New York City.

"John Wick 3: Parabellum" opens in theaters May 17, 2019.
