On the surface, Luce Edgar seems like the perfect son. He’s a star athlete. He’s valedictorian of his entire school. And that’s not even considering his past. He’s a former child soldier from Eritrea who, against all odds, seems to have put his trauma behind him, and formed a healthy, stable social life. “Seems” being the keyword here. See, one day, a teacher asks him to write an essay in the voice of a historical figure, and Luce delivers a piece emulating the style of Frantz Fanon, a pan-Africanist who argued that violence was necessary to settle political disputes. Disturbed, this same teacher breaks into Luce’s locker and discovers fireworks there. She alerts Luce’s parents to both of these things, and while neither of them wants to believe that their son could be capable of violence, as they do more digging, they realize that there might be more to their baby than once thought.
