The new season of "Downton Abbey" is going to heat up. Literally.
The fifth season kicks off on Sunday, Jan. 4 at 9 p.m. on PBS with a fire that rages through the hallowed halls. But that's far from the only drama rocking the passageways of the Crawley residence. Everybody's got secrets, secrets that will make the Dowager Countess (Maggie Smith) make one shocking face. See for yourself in the trailer above.
The tease features some modern music with some very British "Downton Abbey" quotes over scenes from the new season. A sampling of the teasers:
"I have a secret...a bad secret."
"We have to be on our guard."
"You're a very naughty boy."
"No one must ever find out."

Last season was particularly rough for Froggatt's Anna and Coyle's Mr. Bates, but we'll see them start to heal after Anna's brutual attack.
"Anna and Bates do start season five in a more positive place than they were in season four, but obviously such an event is not something that dissipates or goes away. It's something that people live with for the rest of their lives," Froggatt told E! There's still a cloud over Anna and I think she's definitely changed after what's happened to her, but with her and Mr. Bates, they're both trying to get through each day and rebuild their lives together, but as I said there is a cloud hanging over them still."
