Change is in the air in Season 4 as the Pied Piper guys pursue their video-chat app, PiperChat, but Richard has a hard time letting go of his dream to put his algorithm to better use, leaving the team struggling with how they fit into the picture. Meanwhile, Monica deals with new competition in the office, and Gavin faces big changes at Hooli and beyond.

With Richard unexpectedly ousted as CEO, Season 3 picks up with him offered a diminished role of CTO and the rest of his team facing the question of just how far their loyalty extends. Now under a new CEO who is hell-bent on transforming everything from Pied Piper's offices to its business agenda, the guys must find a way to triumph in the war of Art vs. Commerce. Meanwhile, as Gavin Belson works to rehabilitate Hooli's image following his blunders, Big Head finds himself in a new partnership.
