'You don't go to drama school just hoping to do alright. You go because you think you are the greatest actor imaginable, or have the potential of being so.' Five people, including Susannah York and playwright Hugh Whitemore, were all in the same class at the Royal Academy of Dramatic Art over 20 years ago and shared a common ambition. Twenty Years On looks at the different directions their lives have taken, and what happened when they all met for the first time since then.
