Davi is in his second year of high school and finally got the courage to start the astrology course he always wanted to take but never had the courage to admit, for fear of being prejudiced. Between star signs and charts, he meets Milena, an incredible girl, who leaves him enchanted with her passionate way. Tetê, Davi's best friend, encourages him to invest in the relationship, but overcoming shyness is a challenge for him. Helping Zeca, his friend who is going through love problems, is also a difficulty, as Davi is inexperienced in the subject. At the end of the first semester, however, something new causes a stir in the class: Samantha, a classmate of the trio, introduces Gonçalo, who lives in Portugal and came to spend the European summer vacation at her house, in Rio de Janeiro. The arrival of a foreigner has unexpected effects, and Davi and his friends start to deal with issues they never imagined having to face.
