Pie-in-the-sky predictions: the plot is you versus an apocalyptic "killer app" that's taking over the world. I've heard rumors of a robot hand on the playfield, so maybe it's literally player vs machine. "Dialed In" is the name of the software/concept of the machine contacting a cell phone, either a fake one built into the playfield (perhaps like the book in TH, or maybe something near the flippers - it could have a headphone jack and be interactive) or your own phone. Maybe it calls your phone and you listen, via your headphones, to the in-game audio, including a voice that's telling you things, like what shots to shoot, or audio updates on the situation (maybe audio logs - audio log modes?).
Or it could be The Jetsons.
