Like some people recently retired, Mark had taken on a diversion that pretty well takes up much of his time. At one time, he collected baseball cards, a pastime that required him to acquire cards through trades with fellow enthusiasts or winning cards through arcane competitions when the application of Facebook allowed him to accumulate cards more easily. Several years later, on an airplane flight from Montreal to New York City, Mark glimpses a television show being shown on a computer laptop belonging to a woman sitting in a seat across the aisle of that flight. Mark thinks and then becomes convinced that one of the actresses playing a woman in that show is in fact his first girlfriend. That realization results in a search for the identity of that woman though a variety of methods and sources, an effort that culminates in a rendezvous with his memory.
