Synopsis

When Homicide Detective Kang Oh Soo hit a dead end in his investigation of two seemly unrelated murders, except for the Tarot cards left behind at both crime scenes, he sought help from Seo Hae In, a woman with psychometry ability. She revealed that the killers were different in each murder, but the victims were chosen for their connection to a death of a high school boy. Later, the cases proved to have one more thing in common: the suspects have the same defense attorney, Oh Seung Ha. Seung Ha's defense for his clients severely shaken Oh Soo’s conviction to catch the Tarot Card mastermind. Oh Soo was reminded that years ago he had killed a high school classmate in a fight. He was acquitted of all charges and began his life anew. Now, someone has came back to revenge the boy’s wrongful death by killing those who got him off.
