Kim Soo Young (Shin Ha Kyun) is a newly elected member of the Korean National Assembly from the conservative New Korea Party. He entered politics after refusing to bow to pressure from his superiors as a sitting judge. When he arrives in parliament, Soo Young finds that he keeps running into and clashing with Noh Min Young (Lee Min Jung), another freshman assembly member from the liberal Progressive Labor Party who entered politics after the death of her sister. When Soo Young and Min Jung’s fiery exchanges at work turns to romance in their private lives, they must try to hide their relationship from their colleagues, the press, and the public.

Meanwhile, Joon Ha (Park Hee Soon) is a prosecutor who became Noh Min Young’s aide when she’s newly elected to her parliamentary post. Ahn Hee Sun (Han Chae Ah) will be playing a reporter.
