As the Limerick building - and any illusion of safety go - up in flames, Andrew manages to escape the flames with only minor injuries. But he's still trapped in New Winslow as essential ghosts stay silent and those in power attempt to hide the real cause of the fire. As everybody races to solve the curse, long-buried secrets finally explode into view. But, like everything else, they come with a cost.

Iris is so close to solving the mystery of the curse, but what is she willing to do to herself and others to achieve this? And will it be worth the cost? Whatever that cost, Noah is willing to pay it, even at the risk of his hard-won second chance. Andrew, Cleo, and Olivia try to find a safe balance that will let them all move forward, while Roman does what he can from the other side of the town line as his family's future presents itself in surprising ways. It's the end of the line, and the town's past is even louder than its present. So what will be left when the smoke clears?

It's the final season, and it's time to see where the history books lead.
