RIO tells stories about love, the "polyamory", in the broadest sense of the word. Without barriers or prejudices, RIO brings the story of Ricardo, Isabel and Olivia (the initials of their names have a connection with the name of the series), three young middle-class people in a configuration of postmodern family that not only shares the space where they live, but also their fears, anguish, doubts, desires and a whole lot of other feelings. RIO shows the daily life of a triangle that lives in the city, unraveling the sentimental questions of each one without distinguishing sexual orientation. After all, the important thing is to love. And to seek love is to live for it.
