Nights at the Ballet tells the story of a beautiful woman and her treatment at the hands of two unscrupulous men, both vying for supremacy at the pinnacle of the Arts World. Rupert Seymour, Touring Director of the Royal Ballet, astonishes his friends and colleagues by falling in love with another man and abandoning his family after twenty years of marriage. His wife Catherine, deeply shocked, turns for comfort to Rupert's boss, Timothy Jacobs, the rough diamond from television, brought in over Rupert's head to shake up the effete image of the Royal Opera House and make it more accessible to the general public.
