Plot
"Search" At the startup company Comet, several months after the death of his business partner Gordon Clark (Scoot McNairy), Joe MacMillan (Lee Pace) prepares for the relaunch of their website as a web portal, for which his girlfriend Cameron Howe (Mackenzie Davis) led the software development. Joe screens a planned television commercial for the company employees that will accompany the relaunch, and he becomes emotional when seeing footage of Gordon. Later, Joe presents Cameron with a Centipede arcade cabinet, but has another request of her: optimize Comet's performance before the web browser Netscape Navigator is released in hopes of becoming Netscape's default search engine. Cameron reluctantly agrees to stay on longer to help.
Departing for Bangkok, Joanie Clark (Kathryn Newton) bids her mother Donna Emerson (Kerry Bishé) and sister Haley (Susanna Skaggs) farewell at the airport. Diane Gould (Annabeth Gish) stops by Donna's house to tell her she must decide whether or not to succeed Diane as managing partner at their venture capital firm AGGEK. Donna remains unsure what to do. After receiving a clean bill of health, John Bosworth (Toby Huss) tells his wife Diane that he is ready to travel the world together.
Donna and Haley have dinner with Joe and Cameron. Donna expresses interest in being more involved with the creative side of projects. After Joe shows Haley the commercial, she lashes out at him for including footage of her deceased father and for profiting from her idea; Joe decides not to air the commercial. Haley works up the courage to ask a fast food waitress out on a date but is rejected. Donna decides to accept the managing partner position.
While Joe and Cameron review a beta version of Netscape Navigator that her financier Alexa Vonn (Molly Ephraim) had sent her, they find a hyperlink to Yahoo!, an upstart web portal, is prominently placed on the browser's toolbar. Joe realizes that Yahoo! has struck a deal to become Netscape's default search provider and that Comet is doomed. After one last night together, Joe and Cameron break up. When Donna is announced as the new managing partner at AGGEK, Trip Kisker III (Charlie Bodin) informs her that Yahoo!'s rise will mean the end of Comet, and that AGGEK will explore selling Rover's search algorithm so it can revert to its original purpose, indexing medical records. Donna laughs incredulously while repeating the Yahoo! name. Cameron decides to accompany Alexa on an overseas trip to a technology conference.
