In a fractured Britain, The Bloods, a US-backed Christian militia, declare the Second Coming of the Messiah and exile Muslims to refugee camps in Birmingham. Marah loses contact with her lover, Ash, and is kidnapped by The Bloods, who impregnate her with the sperm of the dying King of England. Marah's escape attempts fail, and she discovers her best friend, Leena, is also held captive. Unbeknownst to Marah, Leena is a member of the English Socialist Liberation Army (ESLA), which controls Hertfordshire. Leena and Ash help Marah escape, but amid the chaos of war, Marah's feelings for Ash oscillate between love and hatred as she accuses him of betrayal. Marah's survival hinges on the birth of her baby - a child The Bloods have declared as the Second Coming. They will stop at nothing to capture it.
