Introverted programmer Richard and his pals are going nowhere fast--until his website's unique search algorithm becomes the subject of an extreme bidding war.

After taking the tech world by storm with their debut at TechCrunch Disrupt last season, Richard and his Pied Piper team look ahead to a big future--one that's immediately soured by legal woes and petty revenge plans from Hooli overlord Gavin Belson. This season, Monica finds herself torn between her allegiance to Richard and her job working under a new head honcho. Meanwhile, the presence of Richard's departed longtime pal Big Head looms large, as Gavin decides to use him to his fullest potential.

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.
