A Lágrima Secreta (1967)

A young woman lives a life filled with bad choices. At a young age she marries and has a child--with an abusive thief who quickly ends up in prison. Left alone, she takes up with the guy's mate, another thief, who seems to give her some happiness but who also ends up locked up. She then takes up with a series of seedy types who offer nothing but momentary pleasure--if that.
