Music runs deep in singer/songwriter Lionel Richie's life, especially due to the close bond he had with his maternal grandmother, Adelaide Towson, who taught music at Tuskegee University. Although they had an incredible relationship, Richie knows nothing about her ancestry and is driven to solve the mystery surrounding the identity of her father. Richie sets out on a journey that will take him from his childhood neighborhood in Tuskegee to Nashville where his great grandfather helped sow the seeds of the Civil Rights movement. A trip to Chattanooga, Tennessee will uncover more clues to the identity of those who paved the way for him.
