影片以上世纪七八十年代的贝尔法斯特为背景。Terri Hooley是一名激进、叛逆的音乐爱好者。当时由于北爱尔兰问题，贝尔法斯特冲突不断、民不聊生，泰瑞的朋友们都选定了立场，要么拿起武器要么抛弃自己的家乡，但是泰瑞决定在全欧洲最爆炸声不断的街区上开设一家唱片行，并且取名叫 做「美妙的振荡」。泰瑞先后签下了两支乐队Rudi和The Outkasts，但直到他发掘了Feargal Sharkey和The Undertones之后事情才真正开始有所起色。当John Peel在BBC第一电台上连着播放两遍The Undertones的《Teenage Kicks》这棵一幕发生之后，泰瑞的音乐梦想成为了现实。但泰瑞并不是一个完美的英雄，他有着极其自私的一面，影片同时还展现了他作为一名丈夫和父亲极不任负责任，但是最终，你却不能不对这个人物感到敬佩。In 1970s Belfast, Terri Hooley is an idealistic rocker who finds himself caught in the middle of Northern Ireland's bitter Troubles. Seeing a parallel in the chaos with Jamaica, Hooley opens a record shop, Good Vibrations, to help bring reggae music to his city to help encourage some harmony. However, Hooley soon discovers a new music genre, punk rock, and is inspired by its youthful vitality to become an important record producer and promoter of the local scene. In doing so, Hooley would struggle both with the industry's realities and his chaotic personal life that threaten to consume him. However, he would also be instrumental in creating an alternative Irish community that would bridge his land's religious and social rivalries with an art no one expected.
