The Mountaintop begins with Martin Luther King Jr. returning to the Lorraine Motel after his sermon, I've Been To The Mountaintop. King sends his friend to fetch him cigarettes, ultimately leaving him alone in Room 306 as a storm rages outside. Ordering room service, King comes into contact with Camae (Carrie Mae), the mysterious and beautiful maid who strikes King's attention immediately.
The beginning interactions between the two are filled with flirtation and humor but through the night it slowly progresses to something much deeper. King and Camae begin to discuss the hopes and fears that Martin Luther King Jr. has been feeling, forming a connection and understanding between the two. The conversation focuses on the fight for civil rights and reaches the climax when Camae reveals her true intentions for walking into King's motel room that night.
