'Homeland': Exclusive Sneak Peek At Carrie's Big Meltdown In Season 3, Episode 2 'Uh...Oh...Ah...' (VIDEO)

"Homeland" Season 3 (Sundays at 9 p.m. ET on Showtime) kicked off with a bang as Carrie (Claire Danes) became the target of a Senate investigation about the Langley bombing, her relationship with the suspect, Nicholas Brody (Damian Lewis), and her mental health.

And it's only going to get worse for her before it can get better.

We've got an exclusive sneak peek at "Homeland" Season 3, Episode 2, titled "Uh...Oh...Ah..." (above), which shows Carrie having a meltdown and claiming she's "under attack" while trying to convince a reporter that Brody is innocent.

"A week ago, you published a story that an unnamed CIA officer was in a romantic relationship with the Langley bomber," Carrie says.

"And is that officer you?" the reporter asks.

"No -- you're missing the point. No one at the CIA was in a relationship with the Langley bomber," Carrie says emphatically, still maintaining Brody's innocence and trying to convince the reporter that the story was all a set-up to cover "the big lie."

With five curse word bleeps in a minute and a half, you know Carrie's in a real rage -- and for good reason! Watch our sneak peek, above, to see Carrie's biggest surprise yet ... and, no, it's not a happy one.

"Homeland" airs Sundays at 9 p.m. ET on Showtime.
