From the title you may expect something like Inception, but it's not. As korean movies , dramas are always so extraordinary , I really wanted an amazing movie like Inception from Korean industry but this film is not.
This film have a similar background like A Taxi Driver as in both movies,the leads play the important role to rescue others.
This doesn't have good plot. Actions were kinda over , so overall it's not good directed.
-- Overall this movie won't satisfy your expectations from the title and the poster. So it's not that worthy to watch. ????
