Clones are the latest trend in Dramaland and like any trend in this industry, this horse will be beaten long past its expiration. For now, the still fresh topic gets its first drama with "Duel". Whether the clones in what looks like any other crime and suspense drama will be more than a gimmick remains to be seen.
Jang Deuk-cheon (Jeong Jae-yeong) is a detective with an ill daughter. One day he becomes entagled with two clones, one innocent and one evil, and his little girl is kidnapped. The detective begins a chase against great odds to solve the mystery of his situation and find his child before it is too late.
