A mutated Coronavirus from HCoV-229E subspecie was discovered by a University of Cambridge doctorate student in Genetics from a 14th-century Black Death victim and brought to China's Wuhan Institute of Virology for comparative study on SARS-related diseases and formulation of its cure.

But a rogue yet brilliant scientist stole the virus and, with the help of two deadly assassins, tested its potency in China, Europe and America, which led to the COVID-19 pandemic. With the world in total disorder, the Khalifa, disguised as a politically-influential industrial mogul in the United States, teamed-up with the scientist who was able to upgrade the level of evasiveness, transmissibility and pathogenicity of the hybrid virus by genetic engineering, the resultant super bioweapon getting deadlier with the infusion of the ricin poison.

The multi-billionaire Sheikh of the Slaughterers and his Caliphate Army of federated Al-Qaeda/ISIS terrorists acquired the weapons to compel the United Nations to recognize his global hegemony. Failure to abide on his terms would mean worldwide jihad and 21st-century Black Death where the enemy is silent, unseen and unforgiving.

The Al-Qaeda/ISIS caliph intends to unleash a diabolical catastrophe with the infection, poison and death of at least 18 million inhabitants of Arizona, California, and Nevada served by a ricin-poisoned and coronavirus-contaminated Lake Mead water treatment facilities. With the Hoover Dam on the verge of being busted by W80 thermonuclear weapons, the Khalifa's Operation Zulfiqar can bring back to wasteland the American West for generations to come.
