In 1970s New York, a man named the Unmarried Mother enters a bar and starts talking to the bartender. The bartender asks the man how he came to be called the Unmarried Mother. He writes advice columns currently from the perspective of an Unmarried Mother, but his name came from the fact that he was a woman in his past. As a woman, he fell in love with a man who impregnated him and disappeared, leaving him to give birth to a child, who subsequently disappeared. At the hospital, the nurse told the Unmarried Mother that he had male organs, thereby convincing him to transition. The bartender asks the Unmarried Mother if he’d like to go back in time and find his child. He agrees and they go back to Cleveland in the 1960s, where the Unmarried Mother realizes that he is his own mother, father, and child, as well as the bartender. The bartender recruits the Unmarried Mother, who is also himself, to work for the time travel agency. Then, he travels back to the future, where he reflects on the multiplicity of his identity.
