A young amateur astronomer, Leo Biederman, discovers an unusual object in the sky, which turns out to be a comet. After further investigation, it is revealed that the comet is on a collision course with Earth, with the potential to cause catastrophic damage and mass extinction. The United States government, under the leadership of President Tom Beck, confirms the discovery and launches a plan, codenamed "Operation Messiah," to prevent the disaster.

As the mission to save the Earth progresses, the public grapples with the impending doom, while various human stories unfold. Families and individuals face the uncertainty and tumult of the future, exemplifying the resilience of the human spirit in the face of potential tragedy.
