A story of a certain rock star that takes a leap back in time through his memory. After a band`s lead vocalist, Teddy, is murdered, another band member, Jett, loses his enthusiasm for music. One day, he is hit on the head by a robber and loses consciousness. He wakes up having lost all memory of the years after Teddy`s 1988 murder. Through his remaining memories of the pre-1988 years, Jett takes a journey to the past. After a tiff with another band member, Jett quits the band and meets Teddy in a drunken state. When people lose something, they search for it. If they can`t find it, they substitute something else for it. Then, if they aren`t careful, they lose it again. What Teddy forces Jett to recognize are the precious memories of being happy. As a result, Jett renews his love for music and appreciates his present happiness. A piece that deftly weaves music, memory, and the meaning of love into one touching story. (Kim Ji-seok)
