'Under the Dome' Series Finale To Air September 10; Final Two Episodes Preview

The Under the Dome series finale airs September 10 on CBS.

CBS announced today that the Dome in Chester’s Mill will come down and its mysteries revealed during the series finale of Under the Dome on Thursday, September 10. Based on Stephen King’s bestselling novel, Under the Dome debuted Monday, June 24, 2013, and has been one of the most-watched shows on television for the past three summers.

On this week's episode (“Incandescence”), 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 (Eriq La Salle), who is adamant that infected townspeople never escape the Dome

In the September 10 series finale, when the Dome comes down, many questions about its origin and power will be answered, as two groups of residents engage in one final conflict that some won’t survive.

“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,” said Nina Tassler, Chairman, CBS Entertainment. “Dome’s event storytelling and multi-platform business model paved the way for more original summer programming with the successful rollouts of Extant and Zoo. 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.”

All three seasons of Under the Dome will continue to be available for unlimited streaming to fans and members of Amazon’s Prime Video, which has been the exclusive subscription video on demand (SVOD) home for Dome since the show premiered.
