“Submerso” features Nando Oliveira (Cassio Nascimento), a former world surfing champion, bastard son of an aristocrat from a traditional Santa Catarina family. Nando is a well-known figure, an icon and a celebrity in the sport, but, on the other hand, he has always had a wild life, different from what is imagined as the behavior of a top athlete, getting involved in confusions, fights, always present in the most famous ballads in the country.
