Manuzita, in her childhood, was the most loved girl of Brazil. And with the Guerrero brothers, João and Jerônimo, formed the musical group "Patotinha Mágica". A great national sucess in the 80's decade that ended after the end of the group a while later. Ten years later, their ways cross again. The Rio de Janeiro of the 90's decade, the effervescent culture of the age, social and political events, music and fashion are present in Summer 90, a romantic and musical comedy.
