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.
"House of Cards" Season 4 premieres on Netflix on Friday, March 4. Check out the trailer here:
