"House of Cards" season 3 ended hanging but compellingly when it was launched in its entirety last Feb. 27, 2015. Now fans of the political drama television show are anxious to know what's going to happen to fictional American president Frank Underwood in the upcoming fourth season scheduled to premiere March of this year.

According to N4BB, one of the highlights of season four will be finding out whether Claire Underwood will follow through with her announcement to leave Frank for good. It is also speculated that "House of Cards" season four may probably mark a challenge between the Underwood couple for the presidential seat.

It is also reported that Neve Campbell will be joining the cast line-up as a regular in the upcoming season. There is no news yet as to what her role will be in the storyline, but speculations see her as part of a power tandem to go against Frank and Claire.

Another theory is that Campbell may become the next love interest of Frank, considering that his relationship with Claire is on the rocks.

President Frank is played by Academy Award winner Kevin Spacey, and Claire is played by Robin Wright. Other casts of the show include Kate Mara, Michael Kelly, Corey Stoll, Mahershala Ali, Molly Parker and Michel Gill.
