Jackie and Jade set out to find the Snake Talisman in a cave in South America. They cross paths with an egotistical "archaeologist" shooting for a TV show. After catching wind of their quest the "archaeologist" steals the Talisman. Things become more complicated after the Dark Hand shows up.

The Dark Hand, with the power of the Talismans, goes on a crime spree. Although Jackie is eager to leave Section 13 behind, he agrees to help them one last time against the Dark Hand. Meanwhile, Shendu escapes back to the real world and tries to possess Jackie but accidentally possesses Valmont instead.

The Dark Hand goes hunting for the legendary Pan'ku Box which will lead them to the eight Demon Portals. Knowing that the Dark Hand is too strong with the Talismans for Jackie and Uncle to handle alone, Jade recruits El Toro Fuerte and Viper, along with the reformed Tohru, to form the J-Team.

Shendu and the Dark Hand find a clue to the first gate that will enable him to release his sister, the Mountain Demon. Jackie goes to Japan to stop them, while Uncle begins to train his new apprentice, Tohru. Meanwhile Jade causes havoc with a duplication spell.

When her classmates get a tattoo, Jade decides to get one also. The design she chooses, however, comes from a magical book, which has unexpected consequences.

Jackie is excavating some ancient armor when Uncle reveals it is the Armor of the Gods. This ancient suit of armor was worn by the Eight Immortals in their battles against the Demon Sorcerers. It proves quite convenient when the Dark Hand travels to Spain to find the portal of Dai Gui, the Earth Demon. However, sealing Dai Gui is complicated, as Jade used a sleeping potion on Uncle because of his constant complaining.

The Dark Hand releases Bai Tza, the Water Demon. She seeks out her old kingdom – Atlantis, but when she finds it in ruins, she chooses to drown San Francisco as a new home with some information from Finn. Meanwhile, Valmont manages to render Shendu out cold and seeks help from the Chans to exorcise him from his body. However as Uncle is preoccupied with finding a spell to stop the flood, so the Chans with Valmont have to face Bai Tza without him.

Before Bai Tza can use another flood, Uncle uses a gourd from one of the Immortals to seal her away again. Unfortunately, Jade steps too close to the chi spell and is dragged into Bai Sa's portal. Meanwhile, the Demon Sorcerers communicate with and confront Shendu. In order to escape punishment, he promises that all seven of the Demons can use his own Portal – the only one left – to come back to Earth. A race against time ensues as the Chans work from both sides to both recover Jade and close the last portal for good.

Shendu alters the Book of Ages, and changes history. In a world where demons rule, Jade remembers how things were, and must convince her Uncles to help her set things right.

Jade, Uncle, and Jackie escape from Shendu's palace with a few talismans taken from Shendu. Using Jade's memories of the Immortal symbols, they embark on a mission to find the other members of the J-Team and manage to banish half of the Demons in the process. Realizing what has transpired, Shendu and the other three remaining Demons make a final stand at Australia to prevent history from being corrected.
