Armpits (2016)

Lazarus de Jesus is the adopted son of a wealthy lady from Lisbon, whom he calls Grandmother. It is she who introduces him to Godfather, a great businessman who takes him as his protégé, and Angelina, the woman Grandma wants him to marry. But Lazarus has other hidden interests, the most important of which is an obsessive fixation on female armpits. When he sees the violinist Maria Pia playing, Lazarus immediately falls in love and starts to live for her, which will precipitate an absolutely unpredictable ending.
