Troop 491: The Adventures of the Muddy Lions follows Tristan, a naïve adolescent boy coping with life in the projects. He is enrolled in the Boy Scouts by his mother in an effort to keep him off the streets, but when he witnesses a homicide, the local thug demands his silence. Tristan must learn, with the help of his new friends, that doing the right thing isn't always easy. Will he follow the code of the streets or the code of the scouts?
