In the Queluz-Belas area, on the Sintra Line, Edi, Yuri, and Válter are surrounded by crime: gangs, drug trafficking, robberies; situations that have become normal for them. Their time is divided between school and the time they spend together writing lyrics, listening to music, and walking along the Sintra Line. Under pressure from Jay Dogg, the leader of the RXR Boyz, the three boys will have to decide which side of the line they want to be on, ultimately having to make choices that could completely change their lives.
