With all possible human intervention exhausted, the Earth will imminently be obliterated by a meteorite. As such, most people are putting known laws, rules and conventions aside as they plan for what they really want for the end of their life. Among those making such a decision is Linda Petersen, who leaves her insurance salesman husband Dodge Petersen without a word three weeks before doomsday. Now all alone in the world as his mother passed and his father abandoned the family when he was a child, Dodge does not want to find someone new and strike a relationship with her all in three weeks just to have someone with who to die, despite he marrying Linda so that he would not be all alone in the world. But he does begin to think about Olivia Covello, his high school sweetheart and who he now believes was and should be the love of his life. In these final weeks, Dodge meets his younger Brit downstairs neighbor Penny Lockhart, a hyper-insomniac once she does fall asleep and a vinyl audiophile. Penny is also somewhat alone now that she has broken up with her live-in boyfriend Owen and as her family is back in England. Out of circumstances, Dodge and Penny decide to help each other with their somewhat competing end of the world goals. First, Dodge, who has recently found out that Olivia feels the same about him, wants to find her, with only scant leads on her location. And second, Penny wants to be with her family in England, Dodge who knows a pilot with a plane that may be able to get her there. As they go on their road trip, they have to improvise as they hit one figurative roadblock after another, and deal with what end up being emerging new priorities.
