In 1994 during the IMF crisis, two people meet while exchanging stories on a radio program. They fall in love, but can't quite seem to get the timing right.

While the Goryo Dynasty in the medieval Korea, three warriors named Deok-ki, Poong-chun and Seol-rang have led a riot against the king and his foreign allies from Kitan, China. But Deok-ki betrays them, which results in the death of Poong-chun. But Seol-rang is able to escape with Seol-hee, Poong-chun's little daughter, and her sword. 18 years later, Seol-rang got blind but she raised and taught Seol-hee very well. Both feel that the time for revenge is right, but Deok-ki is now one of the most powerful men in the country. All of them know, that spilling blood is the only way of redemption.

Bok-Soon (KIM Go-Eun) runs a street stall while taking care of her younger sister. Bok-Soon may not be the brightest girl but what she lacks in intelligence, she makes up for in uncontrollable rage. She's infamously known as the 'psycho bitch' in her neighborhood. Bok-Soon's relatively peaceful life with her sister is disrupted when they cross paths with a serial killer named Tae-Soo (LEE Min-Ki). Tae-Soo kills Bok-Soon's sister because she may have stumbled upon the truth of his murderous lifestyle. Bok-Soon's rage consumes her completely, leading her to plot her revenge on Tae Soo. Meanwhile, Tae-Soo vows to tie up his only loose end-Bok-Soon. Bok-Soon's descent into revenge and electrifying struggle with Tae-Soo culminates in a riveting conclusion. Who will emerge alive: hot-blooded Bok-Soon or cold-hearted Tae-Soo?
