Roland Emmerich directs this political thriller based around the notion that William Shakespeare was not in fact the author of the canon of plays attributed to him. In Elizabethan England, political intrigue abounds as the Tudors and the Cecils battle it out over the succession of Queen Elizabeth I (Joely Richardson/Vanessa Redgrave), and the Essex Rebellion mobilises against her. Enter the dashing and wildly talented Edward de Vere, 17th Earl of Oxford (Jamie Campbell Bower/Rhys Ifans), who not only fathers an illegitimate son in a clandestine incestuous relationship with Queen Elizabeth, but is also the secret author of the plays labeled with the name of William Shakespeare (Rafe Spall).

Social psychologist Ben Monroe has returned to Tokyo after a failed marriage, determined to seek out his former lover Kozue. His estranged teenage daughter Mazzy reluctantly flies from California to join him. On the flight she meets a young Japanese man, Koji, a cult survivor, who tells her the story of the luminous night princess Kaguya, a powerful tale of beauty and obsession. As Ben delves deeper into the underworld in search of Kozue, Mazzy and Koji are compelled to follow, and their four lives dangerously intersect as past and present collide.
