The plot: Only the professor, Mary Ann, and Gilligan are still alive when their island is "discovered" by the NSA looking for a remote drone site. Upon reaching the mainland, the professor discovers that a patent he took out years ago for a numbering identification system for computers has become the standard IP addressing used today. Mary Ann is met by her family from Nebraska (?) USA who have never given up hope for her being alive. They reveal that they've gradually sold off the family farm to real estate developers and that she is rich, for her part of the fortune they have made. Mary Ann helps the professor get a huge settlement for his patent rights and he surrounds himself with young geniuses to start his own technology company. Meanwhile Gilligan becomes a media star, appearing on Oprah and similar shows, and his own book, website and so forth. But he quickly tires of how shallow people are and how short the attention span of the media has become. Increasingly disillusioned, he is shocked when an ex-Navy officer reveals to him that it is believed that the skipper caused the shipwreck because he wanted to hide out from charges the navy was bringing against him, rising from an incident when he was in the Navy and that he never intended to take all the castaways with him. Gilligan cannot go back to the island, which is now a tourist spot. He instead buys a house in Hawaii with a private beach and becomes a recluse, staring out to sea.
