交工，指美濃菸農在農忙時期，農家彼此「交換勞力、互相幫助」的習俗，也是交工樂隊取命效法的精神。1999 年，交工樂隊成立，早期因反美濃水庫而受到重視，當 2000 年宣佈水庫停止興建後，他們仍在美濃菸樓錄製專輯，繼續關注農民與農村議題，因為創作的概念始終是為農民發聲。本片是台灣第一部抗爭音樂紀錄片。片中包含演出、創作歷程、反水庫抗議，以及錄製《菊花夜行軍》的片段。導演回溯交工樂隊成團之初到末了，看音樂人和社會運動，客家傳統與現代音樂交織出的在地歌謠；也聚焦細微末節，看團員談笑、點煙、歌唱，深情貼近美濃土地。

“County Road 184” is a documentary about the folk-rock group Labor Exchange Band and the social movement from which it emerged.  In the mid-1990s, the Taiwanese government announced plans to construct a dam in southern Taiwan that would have effectively wiped out the farming town of Meinung. This prompted Meinung residents to form a grassroots movement that successfully stopped construction of the dam, a significant accomplishment at the time in light of Taiwan’s transition to a more open democracy. Labor Exchange played an important role in bringing national attention to Meinung’s anti-dam movement, and today the now-defunct group is still heralded by Taiwanese rock and pop fans as a prime example of how music can influence social change in the country. This film looks at the inspiration behind Labor Exchange’s music, and how its members viewed the movement, both as musicians and activists.
