What if you had a vision that something terrible was going to happen? A train crash, a department store fire, an assassination. What if you could share your vision, and prevent a disaster?

In 1966, John Barker, a British psychiatrist working in an outdated British mental hospital, established the Premonitions Bureau to investigate this very idea. He would find a network of curious correspondents, and among them two highly gifted ‘percipients’.

Together, they predicted calamities and international incidents with uncanny accuracy. And then, they gave Barker their most disturbing warning: that he was about to die.
