The year is 2022, and after an unlikely event, only one man is left on earth: Phil Miller, who used to be just an average guy who loved his family and hated his job at the bank. Now, in his RV, Phil searches the country for other survivors.
Phil and Carol reconcile their differences.
The cul de sac decides to have a re-election for the President of the United States.
Phil attempts to alter his "Alive in Tucson" signs so no more men will show up, but he ends up marooned on one of his billboards with no one to help.
Once Phil fails to convince everyone that his running off with Gail and Erica was a prank, he chooses a much different and entirely unexpected strategy.
With Carol now living in Phil’s house and reorganizing his entire life, he asks God for a “do-over” on his entire life, and unfortunately, he gets one.
Despite Carol nagging him, Todd’s happiness, and Melissa’s complete disinterest, Phil makes a discovery that is going to change the game. Literally.
Todd and Melissa drive Phil crazy with their constant love-making and cutesy behavior. Meanwhile, the community comes together and votes to force Phil to clean his toilet pool.
The discovery of a fourth survivor further complicates things for Phil.
Re-population is the talk of Tucson as Phil navigates the choppy waters between Carol and Melissa.
Phil and Carol are shocked to find Melissa, another survivor, just after Phil reluctantly agreed to marry Carol.
While Carol puts lots of thought and care into her wedding, Phil does his best to pretend like it is not happening.
He has traveled to every city, every town and every outpost in the United States, Mexico and Canada, and has found no one. As he returns to his hometown of Tucson, Phil comes to the realization that he is almost certainly the last living being on the face of the earth.
