A 70-mile-wide asteroid is en route to Earth, and the last best attempt to counter it has failed. Also failing is the marriage of soft-spoken insurance salesman Dodge; the breaking news that the world will end in an estimated 21 days cues his wife to leave him on the spot. Dodge is a man who has always played by the rules of life, while his neighbor Penny is an extroverted woman who hasn't. From these opposite perspectives, both initially choose to navigate the impending end of the world with blinders on. Dodge declines joining his friends in increasingly reckless behavior, while Penny fixates on her relationship issues with a self-absorbed musician.
