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.
