Jeremy Brightside, a frustrated actor, decides to give his career a boost and carry his performances to a wider audience. Dressed in Elizabethan costume he accosts a policeman in London's Piccadilly Circus, which leads him to the courts where he continues his act. He takes on the medical profession, hoodwinking doctors in a series of guises and mimicking medical conditions. Brightside lives each role to the full, subverting the Law as he trails chaos and uncertainty in his wake. Between shows, he conducts a platonic relationship with his Irish landlady from whom he receives encouragement and afternoon tea.

But is he mad, bad or just has a head full of Foolish Notions?

To a Louse, by Robert Burns
