Young residents of Seoul meet, separate, wait and dream by the Inner Circle Line of the Seoul subway system.
A female club DJ becomes attracted to a mysterious club patron who reminds her of a past love. A locomotive engineer is haunted by a suicide in front of his train, and by his past. When the DJs roommate brings things to a head, the two love stories intertwine, like the Inner Circle Line.—Eunhee Cho/Alan T. Chan
