‘Under the Dome’ Preview: Big Jim and Junior square off

The tension that has been brewing for years between Big Jim and Junior comes to a head in the next episode of Under the Dome. While both men have proven to be ruthless and have no problems killing others, will father or son actually kill the other?

Thicker than Water” focuses on the dwindling water sources in Chester’s Mill. Last week, Big Jim took out Ollie’s guard so along with Linda and Barbie, heads over to claim the water as town property. But Ollie and his mini-militia are not okay with that and take decisive action to make it clear that the water is his and anyone siding with Big Jim is an enemy.

Junior offers to help Ollie out, much to his father’s dismay, but things turn ugly even faster when he learns the truth about his mother’s death. We all know Junior is crazy, but does he have it in him to end his father’s life once and for all? Or will Big Jim once again find a way to silence his enemies?

Under the Dome airs Monday, Aug. 12 at 10/9c on CBS.
