Plot details are sparse for John Wick 4, but given Parabellum picked up within seconds of Chapter 2's cliffhanger ending, it stands to reason that the plot will involve John and the Bowery King teaming up to take on the global High Table on their own turf. That could mean that Wick gets to return to his roots as a covert assassin — his targets at this point believe him dead — though given the series' penchant for escalation, it's unlikely things will stay quiet for long.
