Giuseppe Garibaldi (Gabriel Braga Nunes), 32 years old, commander of the republican rebels that invade Laguna, Santa Catarina, during the Farrapos War (1835 - 1845), finds his soul mate in Anita (Ana Paula Arósio), 18 years old, wife of local shoemaker. Between passion and battles, they will define the course of their lives and influence the course of the revolution.

The plot deals with the developments in an old decadent village after a stranger arrives at the old train station, an event in itself. This stranger is a Brazilian musician who carries and plays his "oboe". The music from the oboe, the musician's instrument, will change the lives of everyone involved, and that small village itself will forever be changed by the sound of the oboe.

Raised in a conservative home, Engraçadinha challenges taboos and forbidden passions over two decades. Between desires, guilt and secrets, she lives intensely her loves and her sins.
