Mariana is a little coastal city which every year turns into the big music festival stage "Águas Sonoras". During two days, the tranquility of Mariana gives way to a frenzied frenzy of young people in and around the city. Daniel Vandres is the vocalist of the band "Sound of Silence", the main attraction of the festival. He, however, did not imagine that he would cross the path of the dreamy Josy who just think about work but it is convinced by her sister to go to the festival to have some fun. Roberta nurtures a platonic love for Daniel since childhood and is capable of any madness for the singer to notice her. It is in the middle of one of this madness that they know Beto and Miguel, two boys who will make Josy rethink a little about her concepts of fun.
