When Aku is reborn to set forth his reign of terror, the Emperor's son is sent off to learn the ways of the samurai. That boy becomes a man and attempts to slay Aku with a mighty sword, but Aku banishes him to the future.

The Samurai lands in the future and is named Jack. He is enlisted by a race of dogs to destroy Aku.

Jack gets weapons and beats back Aku's army of beetles saving the canine race.

When a band of bikes mow over Jack's sandals, he goes on a hunt for the perfect footwear.

Jack boards a train to his next destination only to be attacked by a couple of arguing bounty hunters.

Jack and a Swamp Wizard travel to the four corners of the earth, collecting pieces that are meant to get Jack home. But when Aku reveals himself to be the Swamp Wizard, Jack must battle these pieces which are now being puppeteered by Aku's evil hands.

When Aku catches a cold and sneezes on Jack, Jack becomes infected with Aku’s badness which begins to take over his entire body.

Jack helps save a Prince and Princess whose ship has been shot down to Earth by Aku.
