The protagonist Chuck, played by Zachary Levi, interviews for a job at Roark Industries with the goal of hiring on to investigate a possible computer virus, while his father, Stephen J. Bartowski (Scott Bakula), returns home.
The reunion becomes more awkward when Stephen rants about many things he claims to have invented that were stolen by Ted Roark (Chevy Chase).
Among his father's possessions is an advertisement for a major tech show where Roark's latest computer operating system is to be released, which Chuck flashes on.
He realizes that Roark is building a full-scale Intersect system for Fulcrum, but Casey and Sarah don't believe him without solid proof.
Back at Castle, Beckman makes clear the consequences of Roark escaping both with the Intersect and Orion, but tells them that she will put the government's best team on it.
Chuck convinces Beckman that Operation Bartowski is her best team, and demands to be part of the effort to rescue his father.
Bakula and Chase were announced to be playing the roles of Stephen Bartowski and Ted Roark, respectively, in January, 2009 as part of an extended arc to close out the season.
IGN.com rated the episode a 9/10, praising the gravity Chase brought to Ted Roark, and the offbeat and semi-crazy angle Bakula uses to approach Stephen Bartowski.
