From April 26th to May 25th in 1991, 11 Korean young men lost their lives while protesting against injustice of the state. The state imputed the death of the young men to a 27-year-old man, Kang Kihoon. He was found not guilty in 24 years finally. Now, Kang stops his words that he had to say over and over for 20 years, and starts to play the guitar in this film. Other comrades who survived to the last in 1991 also begin to tell their sealed memories.
