Plot
Alan Gould, a neurotic, unkempt anthropology graduate student, is beginning to believe that he may be the last living person on the planet. A mysterious catastrophe appears to have killed off everyone but him, leaving the buildings standing and goods untouched. When he's not running around in his underwear, revelling in his newly found freedom from body-shaming, he's in the abandoned stores downtown trying stuff out. Alan acquires a video camera on one of his expeditions and decides to make a video log explaining to any alien race that stumbles upon the empty planet what he thinks went wrong, interjected with references to his fieldwork among the primitive Shitabi tribe of the Amazon basin. He also tries, mostly unsuccessfully, to embrace the peaceful philosophy of the Shitabi people.
One day, much to Alan's delight, he finds Sarah. She is tall and shapely, but she is also fickle. Before the apocalypse, she wouldn't have spent time with Alan even if he was the last man on Earth. Sarah was the type of person who would sleep with her friend's lover or her lover's friends, and now she has convinced herself God is punishing her for her sins. She doesn't consider Alan to be an ideal mate, but he is all she has now. Alan, for his part, falls in love with her, and he convinces her that they will have to repopulate the world. She in turn makes him promise he will never leave her, and though she shies away from his touch, she reluctantly joins him in his RV.
