When a beautiful black woman arrives on a horse at the gates of Downing Street, demanding immediate access, James Cleveland, PM, is alarmed. Despite his orders for her arrest, she succeeds in reaching him. She informs him that she is the Second Coming of Jesus and, on this second visit to earth, she has come to judge. A series of apparent coincidences dents the general scepticism about her authenticity. As the scion of God, she then exercises an inexplicable coercive power to eliminate several high profile politicians and to persuade world leaders to address global problems with the required sense of urgency. Her success and her authority ends when she suddenly loses her powers. She is arrested and handed over to the security services. But they soon discover that the Second Coming will not end in the same way as the first.
