In this series in the "NinjaGo" franchise, Krux has the ability to go back in time and pause time, while brother Acronix can go into the future and slow down time. They use their powers to control all of NinjaGo and want to undo history and revert the land back to the past. The ninjas must retrieve lost time blades -- which they use to battle the brothers -- to stop Krux and Acronix, who became lost in time after going through the time vortex before the time blades went missing.
