This music documentary follows the path of Yoon Do-hyun Band on its daring adventure of a tour of Europe. During the month-long tour of Europe, sharing a bus with an unknown British rock band, the band members are faced with the challenge of performing for 2 hours in front of an audience of 20. Such experience brings them back to where everything started. What they were faced with was not a new audience but perhaps their own forgotten selves.
