Here's how it works: At first the story is completely separate, one following the actors, one following the viewers. The actors have a crew and everything, but then eventually they discover that they can communicate with the group that is watching TV. The group watching TV is well freaked out, and so are the crew, who are trying to talk to the actors, who seem to be talking to themselves. So as the story progresses the actors have to learn how to communicate to the people watching, but without the crew seeing them do it (or the crew will start asking questions again). So basically the actors have a script to follow, and a director to please. But at the same time they are trying to get a message across to the public. Then the viewers go and get it done, or work towards it so they can do it when they get off work.
