England, 1956. Hollywood's biggest star-Marilyn Monroe-desperately needs time away from a difficult movie shoot opposite Laurence Olivier and the pressures of her new marriage to the playwright Arthur Miller. She turns her attention to Colin Clark, a young and handsome assistant on the set. Together they escape, beginning a remarkable true adventure: an innocent week in the English countryside in which Clark becomes Marilyn's confidant and ally ... and maybe falls a bit in love.
