Synopsis: It's the late '60s and the British Invasion has conquered the world! The Liverpool Sound tops the charts in every country, except in Ireland, where traditional Irish music still reigns supreme! But could the unthinkable happen? Could an upstart Irish band from Liverpool win the All Irish Music Championship for the first time in history? Transplanted Irishman Jimmy McMahon and his motley English crew have their hearts set on it. Meanwhile, back in County Clare, Ireland, Jimmy's stalwart older brother, John Joe and his feisty local band are determined to win the trophy for the third year in a row.
