Unable to find the formula for the antidote, JACK and BRAY must attempt to analyse what little remains while trying to keep it out of the hands of LEX, while TAI SAN puts her trust in herbal medicine. The grateful city dwellers soon turn nasty when they suspect the Mallrats of keeping the antidote for themselves, and – as the Virus begins to spread beyond the city – ALICE takes charge of an angry and desperate mob looking for answers.
The tribe returns to the mall only to find an unwelcome guest lurking in the shadows. Elsewhere, BRAY tries to convince a mistrustful DANNI of his motives, while EBONY attempts to lure LEX back to the dark side. With the antidote in their possession the Mallrats face a dilemma over sharing it with the rest of the city, but without the formula to be able to produce more have they only earned themselves a temporary reprieve?
The Mallrats discover that there is an antidote to the Virus but their joy is short-lived when an explosion at Eagle Mountain has tragic consequences. In their grief, TAI SAN rallies the tribe to return to the city to search for the antidote that could save all their lives, although EBONY has her own reasons for wanting it. Meanwhile, a new tribe spot the satellite in the sky and begin a journey of their own.
The Mallrats have encountered a literal roadblock on their way to Eagle Mountain, but they’re saved by the sudden arrival of BRAY and EBONY in one of the Locos’ buses. BRAY’s reception by AMBER, however, is chilly, much to his confusion. But just when all hope seems to be lost, the Mallrats finally reach their destination and are delivered one final message from the long-lost adults, which places them securely in the driver’s seat of their own destiny.
Prompted by JACK’s insistence and TAI SAN’s vision, which seems to confirm his hunch, the Mallrats agree to leave their home for Eagle Mountain. At the Locos’ headquarters, BRAY attempts to convince EBONY to leave the notorious gang and come back to the mall with him. Her feelings on the topic change drastically when SPIKE initiates his own coup d’état. As the remaining Mallrats begin to leave, AMBER’s finally written off her feelings for BRAY, but TRUDY may not let her give up so easily.
JACK believes he’s uncovered the secret to the mysterious formula, but he has a hard time convincing the others to go along with his hunch since it means potentially leaving the mall for good. AMBER remains on edge after seeing the helicopter footage of BRAY and EBONY together. Meanwhile, EBONY attempts to instill doubt of AMBER’s true feelings into BRAY’s head.
EBONY seems to have won, having taken not only the antidote, but also LEX and BRAY. But AMBER’s not giving BRAY up so easily, and she embarks on a search for the Locos’ hideout. Meanwhile, JACK attempts to access the facility’s files with the help of KC, who fears that his time with the Mallrats is limited.
In his efforts to help CLOE escape the casino, KC has been captured. To continue the clearing of his conscience, LEX sets out to rescue KC, though the young gambler may not be welcomed back to the mall. ZANDRA once again confides in RYAN. And AMBER and BRAY finally reveal their newly minted relationship to the others, only after TRUDY accidentally catches them together.
KC is gambling away the tribe members’ personal items, including the pig! Can CLOE help win it all back? Meanwhile, LEX is feeling the effects of the virus and, having seen TAI SAN’s recovery, decides to try her method instead of taking the antidote. However, TAI SAN’s method requires LEX to be free of a heavy conscience, leading him to a series of confessions to each member of the Mallrats.
AMBER, BRAY, LEX, and DAL are trapped inside the lab at Hope Island with little time to escape before “full decontamination” of the facility is initiated. Elsewhere, TAI SAN’s symptoms worsen, despite her regular meditation. And CLOE stumbles upon a discovery about KC that could mean the end for the tribe’s pet pig!
AMBER, BRAY, LEX, and DAL head to Hope Island with the belief that they’ll find information about a cure for the virus. Unfortunately, what they find en route is an abandoned minefield! Meanwhile TAI SAN begins showing symptoms of the virus, but refuses to treat it with science or technology. And RYAN catches SALENE in the act of bingeing once again.
