After several rounds of fierce competition, the new US President Garrett Walker (Michael Gill) was born, and Francis Underwood (Kevin Spacey), the House Majority Whip who claimed to be a plumber, played an indispensable role behind it. However, the arrogant politician Francis did not become the Secretary of State as he wished, and he was furious about it, and vowed to pull Walker, who betrayed him, off the throne. Using the comprehensive education reform law that the new president intends to promote, Francis manipulated Zoe Barnes (Kate Mara), a female reporter of the Washington Herald, to make a fuss. After the initial victory, he immediately assigned his men to launch a new encirclement and suppression of the new government, while cleverly resolving and avoiding the open and hidden arrows from political enemies. He is like a venomous snake from the Garden of Eden, eloquent, turning the tide, and biting everyone's weaknesses tightly to achieve his goals. “There are no eternal enemies, only eternal interests”, this sentence is best reflected in Francis.
