Returning to Earth after their run-in with Vorjak (Kerry Dorey), Renee (Jayne Heitmeyer) and Liam (Robert Leeshock) meet with Hubble Urick (Frank Moore). He tells them that the Taelons are no longer welcome on Earth. He's fully prepared to blow up the Mothership, if need be, in order to keep them away. Worried about the Taelons' safety and future, Liam and Renee ask J. Street (Melinda Deines) to solve the final dimension of Ma'el's relic, which holds the secret of life for the Taelons. Street refuses to help because of the demands of multi-dimensional thinking, a unique ability she considers a curse. Liam and Renee decide to get the remaining Taelons on the Mothership into stasis.

Later that night, Street is out at a dance club when a strobe light near the dance floor suddenly sends her into a multi-dimensional trance. She is swiftly engulfed in a cyclone of white light. At the White House, Hubble and an Air Force General see a white light at the same time that Zo'or (Anita La Selva) and Da'an (Leni Parker) witness it from the Mothership.

The light is also observed by Liam and Renee. They take off on a shuttle in search of the source, which turns out to be a volcano in Southern Asia. The craft is caught in a beam of energy that pulls them down, forcing a bumpy landing adjacent to a lava tube that leads to the volcano's interior. Liam and Renee enter the tube, and find themselves in a chamber with ancient Taelon hieroglyphics on the walls. The two agree that Ma'el must have been there close to 2,000 years ago. Searching around, Liam finds a portal. Entering through it, he winds up in another chamber containing sarcophagus-like containers and a pool of liquid energy. Liam tries to return to Renee through the portal, but realizes he is trapped.

Elsewhere, a Jaridian ship carrying Vorjak and a band of Jaridians approaches the Mothership. Street arrives at the volcano with Augur (Richard Chevolleau). She tries to fix the portal that has trapped Liam. Augur is suddenly jolted by a burst of energy that produces a hologram of Ma'el. He tells them of the Atavus, the Taelon proto species found at the volcano after his spaceship had crashed there years ago. He explains that the chamber in which Liam is trapped is actually a healing chamber built by Ma'el to regenerate the Taelons. Liam sends Renee to fetch Da'an and five other Taelons, knowing that the Atavan energy pool is the only chance for the Taelon species to survive.

While Da'an decides which five Taelons to take with him to the Atavan chamber, Zo'or steals Ma'el's relic, a key component of the Atavan energy-transfer process. Back in the chamber, Street and Augur unintentionally activate the energy pool, giving them less than an hour to complete the procedure. Cracks begin to appear in the chamber's walls, as the volcano prepares to erupt. It is now a race against time for all concerned. When the Jaridians board the Mothership, they find themselves trapped in a force field set by Ronald Sandoval (Von Flores). He strikes a deal, promising to lead them to the Taelons if they spare Earth and elect him ruler of the planet. Sandoval and the Jardians make their way to a portal, just as Hubble opens fire on the ship.

As Sandoval collapses, badly wounded, Vorjak and the others escape. Back at the Atavan chamber, Zo'or appears with Ma'el's relic. Despite Liam's warnings, he dips his hand into the energy pool. Submerging himself in the pool, he sheds his exoskeleton and collapses amidst a blinding whirl of light. Vorjak and his Jaridian shipmates arrive at the chamber just as Liam and Street are about to begin the transfer of Atavan energy to Da'an and the other Taelons.

Street realizes that the only chance of survival for both the Jaridans and Taelons is for them to unite in the chamber. Sending Street, Augur and Renee to the safety of the shuttle, Liam begins the energy-transfer process, knowing it may cost him his life. As his friends speed across the sky, the volcano violently erupts, leaving little possibility for anyone or anything to survive.
