The film tells the story of Eire's seminal rock band Taste, formed in Cork, Ireland in 1966 by Rory Gallagher, Taste had a brief but influential career, releasing two studio albums in 1969 and 1970 and disbanding shortly after their legendary appearance at the 1970 Isle Of Wight Festival, which is the centrepiece of this film.

In August 1970, 600,000 fans flocked to the Isle of Wight to witness the third and final festival to be held on the island. Besides the music, they also got a look at the greed, cynicism and corruption that would plague the music industry for years to come. They also witnessed the final, drugged out performance of Jimi Hendrix in England just two weeks before he would meet a tragic death. When it all was over, the fans view of rock and roll was never the same.
