Vou Rifar Meu Coração is a documentary about the performers and the followers of Brazilian romantic music – also known as brega (kitsch), often called "cheesy" by critics and the wealthy elite. Frequently associated with bad taste and poor quality, the style is admired by the lower working class, or unemployed population, originally from rural origins, banished to the cities in search of work and a better life. Using the music as a catalyst, this documentary shows the sentiments, love, suffering and sexuality of the fans and their idols, creating a scenario that reveals their practices and desires.

Julio is a peaceful, uptight dentist who planned his life 80 years in advance. Suddenly dumped by his girlfriend, he also finds out he is the son of a womanizer, a popular singer of the 1970s, and the brother of an intense gay musician, both of whom he never knew—until now.
