In his new play, Rob Drummond examines science and skepticism. To gather insights, he talks with Mary, a mother striving to make the best choices for her family; Toby, a disillusioned son who distrusts institutions; and Edward Jenner, the pioneer of modern vaccinations. As Rob delves deeper, he finds it increasingly difficult to remain impartial, leading him to question who can truly be trusted. Drummond, known for his 'utterly unpredictable' plays (The Stage), tackles the complex politics of vaccines and the personal stories entwined with them.
