A young boy plays on the floor of a Montgomery, Alabama bus while it is moving. He carefully rolls the marble back and forth in the grooves of the floor when he notices Rosa Parks sitting in the front seat of the bus. She looks worn and tired from a long day at work. Then, at the next stop, a white man gets onto the bus and demands she move out of ‘his’ seat but she refuses. Follow a young bus rider as he witnesses the start of the Montgomery Bus Boycott.
