Once partners in crime, Frank and Claire Underwood seem to be each other's worst enemy on the upcoming fourth season of "House of Cards."

In a new trailer, Frank (Kevin Spacey) tells his estranged wife, in voiceover: "You don't value what we have achieved. I have had to fight for everything my entire life."

"I saw a future - our future," Claire (Robin Wright) responds. "We had a future until you started destroying it," Frank snaps back.

The minute-long teaser offers us glimpses of new cast members, including Neve Campbell and Ellen Burstyn, as well as a number of sex scenes, and a faucet dripping blood.
