The dome is coming down—for good.
CBS announced Monday that the upcoming season three finale of Under the Dome will also serve as its series finale. The episode, which promises answers about the mysterious dome that surrounds the sleepy Maine town of Chester's Mill, is scheduled to air on Thursday, Sept. 10.
The series, which recently attracted 4.6 million viewers, is based on a Stephen King novel—who not only wrote the season two premiere, but also popped by the North Carolina set for a cameo in the episode. The show (and the book of the same name) followed the residents of a town cut off from the rest of the world when a gigantic transparent dome surrounds the city limits, leaving them with spotty radio communication and—gasp!—no cell or Internet service.
CBS assured fans in a press release announcing the news that "many questions about [the dome's] origin and power will be answered, as two groups of residents engage in one final conflict that some won't survive."
Said CBS Entertainment chairman Nina Tassler in a press release, "Two years ago, Under the Dome broke new ground in the summer and became an instant hit on CBS, as well as with viewers around the world. ... We're excited to present the final chapter in Chester's Mill as the story comes full circle, with the Dome coming down as dramatically as it went up."
Under the Dome's series finale will air on Thursday, Sept. 10 on CBS.
