From the moment she first holds him, Gladys Presley loves her son Elvis ferociously. She will be his greatest influence, the love of his life. And he will love her back. But while he makes it big in Hollywood and achieves unimagined wealth and fame, there is another story of drinking and diet pills, loneliness and loss. While the heat and music of the American South play in the background, a heartbreaking portrait of a mother's love and a son's devotion takes centre stage. When Elvis reaches the height of his power, he buys his family the ultimate mansion on the hill, Graceland, where he hopes his mother will be happy. The reality, though, is very different.
