In 1956, Marilyn Monroe and her newlywed husband, the great playwright Arthur Miller, travel to England, where Monroe shoots the costume comedy The Prince and the Showgirl, directed by and alongside Laurence Olivier. Also on the set is young Oxford graduate Colin Clark, who is just entering the film business as a third assistant director. When Miller flies back to the USA, the crisis-ridden world star makes the young Colin more and more her confidant.
