The documentary tells how some rockers from the 1970s decided to use their ingenuity and creativity to combine rock with folklore, giving rise to new sounds that set the musical tone for those years and are now part of our country's musical history. The stories of each of the interviewees strengthen the country's collective memory, and through their anecdotes, the work of this group for Colombian rock is preserved.
