Looking for his estranged biological mother, a young man and his donkey travel to the big city, where the rich widow looks for him at the same time, all for the concern of her ambitious niece craving her wealth.
Rock Story tells the trajectory of the rocker Guilherme Santiago, who was very successful in the 90s and now tries to return to the charts. In the plot, set in Rio, love and music run together, approaching hearts that have the same ideals.
The plot is dictated by the law of return and the belief that one day justice reaches everyone. Sooner or later life will take care of giving the change, and everything one does one day turns against oneself.
The story happens in the centuries 18th and 19th, mostly after Minas Gerais Conspiracy, a Brazilian separatist movement. It mixes fantasy with real history facts. Some of the characters did exist in real life, such as John VI of Portugal.
