Ty Brown is Executive Director of Brooklyn United, a marching band, one hundred fifty strong. As Ty states, BU is what keeps these young people off the streets, from gangs and worse. BU opens with drummer, Brandon Little, who raps BU's story from the beginning to the present. During the film, we experience Ty's sudden fall from grace due to alleged sexual misconduct with an underage female band member and Ty's path of redemption and rebirth after a long exile form all he's ever known.
