Season 1

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.

Phil finds out he's not the last person left on Earth, but things aren't as wonderful as he would have hoped.

Phil's prayers have been answered—sort of—now that he has found the last woman on earth, Carol. He finds himself back among human existence, and somehow engaged to be married.

Phil and Carol are shocked to find Melissa, another survivor, just after Phil reluctantly agreed to marry Carol. Phil finds himself in a pickle and has to work fast in order to save human existence.

Re-population is the talk of Tucson as Phil navigates the choppy waters between Carol and Melissa.

Phil Miller continues to live in Tucson.

The knowledge that Todd and Melissa are having sex drives Phil to manic despair, so Phil arranges a community meeting to discuss grievances. However, his plans go awry when everyone instead agrees that he should clean out the pool he has been using as a toilet. The next day, Phil schemes to leave Todd in the desert to die, but his conscience prevents him from doing so. Todd expresses gratitude to Phil for helping him find his way to Tucson, which motivates Phil to finally clean out his toilet pool and bring an outhouse into his home, much to Carol's delight.

Phil becomes annoyed at all the attention Todd is receiving and schemes to bring the attention back to himself when he finds a stray cow. To do so, he pretends to steal the cow, but when he really does lose it, Todd eventually finds it and allows Phil to take the credit. That night, the group discovers that the cow has apparently wandered up the stairs of Carol's house and is now stranded, causing Carol to officially move in with Phil. In a brief flashback, Carol is seen purposely bringing the cow upstairs.

The cul de sac decides to have a re-election for the President of the United States.

Everyone is mad at Phil for lying as they refuse to speak to Phil, and he is shunned. Carol also holds a grudge against Erica and Gail. Phil confronts the group and tells the truth about various issues, including the fact that he never wanted to marry Carol. Carol, who is a notary, divorces Phil, then forgives him and invites him back to the cul-de-sac.

Phil Miller continues his life.
