• Pan-Continental airline pilot Rayford Steele
• Global Weekly senior writer Cameron (Buck) Williams
• New Life Community Church minister Bruce Barnes
• Stanford University student Chloe Steele

These four find the answer in a most surprising and seemingly unlikely place. Suddenly everything makes sense, but they learn that the disappearances have ushered in a seven-year period called the Tribulation, during which the earth will suffer from the most catastrophic calamities in its history.

Those left behind face war, famine, plagues, and natural disasters so devastating that only one in four people will survive. Odds are even worse for enemies of the Antichrist and his new world order.

Rayford Steele, Buck Williams, Bruce Barnes, and Chloe Steele band together to form the Tribulation Force. Their task is clear, and their goal is nothing less than to stand and fight the enemies of God during the seven most chaotic years the planet will ever see.
