2020 is the year in which Noah Daniels lives with his family. Back in 2002 a comet Nemesis destroyed the Earth's surface along with humans and animals. The few that survived live underground in a place called North Col.
After being captured by a group of Nomads, Noah is still trying to figure out how far back into the past he is. The Nomads are a small band of children who are pursued by another older group of youths called the Protectors who runs a mine.
Still a captive of the Nomads, Sundance and Noah come face-to-face with the protectors once again and we discover that Sundance has a twin brother Sutch who is a Protector.
Tao has plans for the truck known as The Beast. The Nomads are still trying to reach the safety of the mountains via the 'deep road', meanwhile Noah has discovered that he is actually in North Col, but instead of being in the past he is in the future year of 2085.
Arushka and Noah sneak into the protector mines in order to save Sundance whom they are convinced.
Noah and Arushka stare gob smacked at the huge creature before them. This is a circus in 1999 — they have gone back too far! Arushka doesn't hear or care about Noah's concerns — these are real animals not just images on a wall. She never wants to leave. Noah tells her in a couple of years the animals and everything else will be gone when the Nemesis Comet strikes. Noah sets off to find a power source, leaving a saddened Arushka to look around. All of the animals are amazing but when she meets the beautiful circus horse Moshi she is totally captivated.
With the scaped lion on the bonnet of the police car, a horrified and amazed crowd watches as Arushka calms him. She achieves instant star status when she gestures the animal back into his cage.
Tao has a plan to capture the Nomads — with the help of his Sentinel he will trap them in their own lair! In the Beast he watches on the screen as Arushka and Chip release Moshi and Noah and Geneva head towards the Mine. He and Jett race across the Red Desert chasing the signal, closing in.
Still trapped under the Beast trailer, Noah and Sundance see Arushka approaching on Moshi. Tao, impressed with her bravery, and interested in Moshi, steps out to confront her, giving Noah and Sundance the chance to get inside the Beast trailer and sabotage the map co-ordinates that would lead to the capture of the Nomads. With the mission accomplished Noah and Sundance say their farewells, Noah heading off to the Keep and a power source for hs PH-Ts.
Noah and Arushka white-in, arriving in some bush country abundant with wildlife, and to Arushka's delight, horses. Her reverie is shattered as gunshots ring through the air. An outraged Arushka runs to the noise and confronts Bully and Mac who are trying to cull kangaroos. Not happy at being interrupted they warn Noah and Arushka off. They are saved from these lads only to be imprisoned by their saviour, Duane, an alien fanatic who saw them arrive. This time they will have to believe him, he has proof!
Arushka, still trapped in the past and hunted by Bully, Mac and Duane, saves Mac from being trampled by a wild brumby. Awed by the mystical effect she has on the animal, they listen to her story. Duane and Mac agree to help her but Bully standing alone is not to be trusted.
Arushka now has the horses she wanted but Noah tells her he can't help her bring back more animals to Haven — he wants to go home. Bidding them farewell he heads off towards the Mine. On the way a brave and loyal Dolly saves him again and his journey must be abandoned.
In the middle of the red desert a furious Tao stands before a burning effigy of himself. Unguarded, the Beast's trailer looms behind. Noah and Arushka enter it and begin the first of many risky sorties to access the power they will need to bring back the wondrous collection of animals that will fill the magnificent landscape that is Haven.
Noah has been forced to give in to Tao, who would have used the destructive Electronet on Dolly's puppies. Now a prisoner in the Keep, Noah discovers Ferris and retrieves his PH-Ts which Ferris has stolen. Noah escapes with Ferris' help only to find Arushka has been captured while trying to rescue the puppies. Noah tries to smash the Net which Tao is trying to lure Dolly into but he is zapped and thrown to the ground, unconscious.
Noah and the Nomads are forced from safety by the Thunderstone smoke that continues to billow out of the Cavern; they are surrounded by Protectors and trapped by the Electronets. If captured they will be unable to stop Tao so Noah, their only hope, must travel back to his time and return with technology to fight the Electronets.
With Noah and Arushka safely imprisoned in the Beast, Tao roars off leaving Chip alone under the relentless sun of the Red Desert. On a rescue mission, Sundance and Becky find him, exhausted and thirsty but alive.
Tao offers Noah a share of the rabies vaccine and power to return to him to North Col. With Noah gone and the maserguns to rid Haven of the animals, Tao is now free to find more Thunderstone.
The thought that he could be the monstrous Shadowmaster tortures Noah as he waits anxiously for the results of his father's tests on vaccine.
Noah cannot believe that he is, or that in the future he will become, the creature that stands before him. The Shadowmaster tells Noah that it is time he learnt the truth. They both white-out of North Col and arrive in Haven.
The Daniels family are blamed for the rabies virus and the North Col community will not listen as Noah tells them the rats weren't real but holograms. Matters worsen when it is discovered the vaccine held as evidence has been stolen. Simon's subsequent collapse causes everyone to panic… he has a virus!
While the unsuspecting citizens of North Col are preparing for their journey to Haven, the Shadowmaster is assuring Tao that a labour force will arrive soon to help in the mining of the Thunderstone. Becky's suspicions are aroused when she sees Dr. Pretorius behaving strangely. As she explores a deserted North Col she discovers that Dr. Pretorius has the missing vaccine in his secret lab. Captured by the Shadowmaster she is forced to join the others in Haven.
In a Topside blizzard the bewildered Nomads make their way into North Col where Geneva guides them to the holodeck. Through a combination of deduction and good luck the Nomads propel themselves forward in time to Haven where their reappearance is monitored by Sutch.
