Leaving war-ravaged London in 1916, Jennifer Doyle and her reprobate father set sail for America. As the boat draws near to the soaring skyscrapers of New York a world of possibilities is promised, so when Jenny discovers that her father has arranged her work with the neurotic Madame de Saulles, she is devastated.
Life at the Box, the home of the de Saulles, is Gatsby-like glamorous but with cloying undertones of malice and madness, and Jenny's blossoming romance with dancer Rodolfo offers rare relief. Secrets infect the household until, one tragic day, the lives of the inhabitants are changed forever.
Years later, Rodolfo has taken his place in the Hollywood pantheon as Rudolph Valentino, the most desired and talked about star of the day. His love for Jenny remains, but fame is all-consuming. When a chance arises for the pair to meet again, can their love story have a Hollywood happy ending, or will the tragic echoes from their time at the Box thwart them one last time?
