The grisly discovery of a body in the woods leads Seo Jae-hyuk (Jun Kwang-ryul) to be involved in an elaborate cover-up and wrongfully accused of murder. Following a rigged trial, he is convicted and sent to prison. Determined to prove his father’s innocence, Seo Jin-woo (Yoo Seung-ho) uses his special ability, hyperthymesia – the ability to perfectly recall every detail from every day, to become the youngest lawyer in South Korea.
However, it is a race against time as his father’s memory begins deteriorating in prison and the day of his execution draws nearer.
