Plot SummaryEdit

"Move On" & "But I'm Not"Edit

The residents of Chester's Mill appear both inside and outside the Dome following their mysterious encounter in the tunnels beneath the town. As the Dome begins to reveal its ultimate agenda, the townspeople are forced to question what and whom they can trust as fresh threats appear, new residents emerge and surprising alliances form.

"Redux"Edit

The residents of Chester's Mill try to move on with their lives in the aftermath of their mysterious experience in the tunnels beneath town. Meanwhile, Big Jim suspects new residents Christine and Eva are keeping secrets concerning the Dome.

"The Kinship"Edit

Under the guise of helping Chester's Mill rebuild, Christine urges the townspeople towards specific individuals and projects that remind them of their experience in the tunnels. Also, Julia and Big Jim make shocking discoveries that reveal a new threat within the Dome.

"Alaska"Edit

Big Jim and Julia form a tentative alliance to search for proof that will discredit Christine, which leads them to new information about the Dome's capabilities. Meanwhile, when tensions run high in town and threaten Christine's leadership, she puts a plan in play that has deadly consequences.

"Caged"Edit

When Big Jim is captured by Aktaion, the dangerous private corporation that’s descended on Chester's Mill to harness the Dome's energy capabilities, he's forced to manipulate Christine for information about her agenda. Also, when Joe and Norrie question the town’s new rules, they find themselves in a dangerous face-off with the increasingly unstable residents.

"Ejecta"Edit

As the world outside the Dome is rocked by a catastrophic meteor shower, unexpected alliances form inside the barrier. Eva tries to indoctrinate Barbie deeper into The Kinship and Big Jim and Julia turn to one another while isolated on Bird Island outside of town. Also, Joe is forced to accept help from Sam, the man who killed his sister.

"Breaking Point"Edit

Big Jim, Julia, Joe, Norrie and Hunter join together to form a resistance against Christine, who is mobilizing residents to work on a massive excavation project in the caves underneath the town. Also, Hunter uses his tech skills to contact the outside world.

"Plan B"Edit

Big Jim and Julia devise plans to end Christine's control over the town by initiating a life-or-death plot involving Barbie and Eva, while Joe and Norrie conduct research to better understand the Dome's ultimate agenda. Meanwhile, Hunter finds more information about the true head of Aktaion, the nefarious private corporation that wants to harness the Dome's energy.

"Legacy"Edit

The Resistance, the citizens not under Christine's control, join forces with an unexpected ally: Hektor Martin, the nefarious head of Aktaion. Despite Hektor revealing more about the Dome's origins and helping to strike back at it, Big Jim and Julia still worry he will betray them. Meanwhile, Hunter receives encrypted files that give disturbing insights into the final effect the Dome will have on the infected townspeople.

"Love is a Battlefield"Edit

Members of The Resistance race to release their loved ones from Christine's influence before she reaches her end game for the Dome. While Barbie risks everything in an attempt to free Eva from The Kinship, Big Jim and Julia are enlisted by Hektor, the head of Aktaion, to test a possible cure for infected townspeople. Also, Joe chooses to work with Christine after she shares some shocking information about the entity behind the Dome.

"Incandescence"Edit

When the Dome's calcification process accelerates, Chester's Mill has 24 hours before the barrier's breakdown will suffocate everyone inside. While the new deadline puts added pressure on Joe to bring the Dome down, Barbie and Julia race to save his child from The Kinship. Also, Big Jim tries to manage the increasingly volatile Hektor, who is adamant that infected townspeople never escape the Dome.

"The Enemy Within"Edit

As the Dome in Chester's Mill comes down, the Resistance makes a final attempt to protect the outside world from the infected townspeople in the Kinship and their new queen.
