Four months after the 1969 Woodstock Music Festival, there was a shooting that was far less famous than the former, but comparable in terms of significance and achievement. This film is about this incident. The band can be said to be the end of rock'n 'roll in the 1960s, but its appearance is December 1969. At that time, the band Rolling Stones, which had a large number of fans in the United States, held a free concert in Oldmond, California, USA. 400000 people came to the concert that day, but a tragedy occurred. The biker gang hired to maintain order staged violent scenes at the concert, and one audience was chased to death. The documentary, also known as "Let me hide", records the most treasured moments of the Rolling Stones and the ferocious figure of Hell Angels, who end up fighting with some of the audience. the huge myth of the gathering of love and peace in the 1960s collapsed in an instant, and because of these incomparably real scenes, the film is of great importance in the rock literature.
