Plot summary Main plot The episode begins with a flashback to 1990 where a young girl is riding her bike, when she is struck by an armored car. When the driver panics and calls for help, a man from another car gets out and says he's a doctor, offering to drive her to the hospital. As he loads her into the car, it is revealed that the girl is Sarah as a child, and that the "doctor" is her father, who used the distraction of a fake accident to rob the armored car. In the present day, Sarah takes a personal day and is evasive with Chuck as to why. He follows her only to find her meeting with an older man at a fancy restaurant, on whom he flashes. However Chuck's watch gives away his location, and Sarah confronts him. Chuck tries to warn Sarah that her date is dangerous. The man overhears them, including insulting comments made by Chuck, when Sarah introduces him as her father, "Jack Burton." The team learns that Jack is in town to meet with Sheik Ahmad, who has terrorist connections. The team is ordered to use Sarah's personal connection to investigate, and locate evidence connecting Ahmad to terrorist activities. Using the cover of dinner, Sarah and Chuck meet with Jack, where he reveals he pulled a scam he calls the "Lichtenstein", selling a building Jack doesn't own, to Sheik Ahmad. Chuck flashes on Ahmad and his men, who confront Jack and attempt to reclaim their money. Jack involves Sarah in his scheme when she comes to help by identifying her as Lichtenstein's assistant, and when Ahmad threatens to kill them, Chuck defuses the situation by pretending to be Lichtenstein himself. A meeting is set at the Nagamichi office tower, which Jack has identified as the fictional Lichtenstein building, to arrange the hand-over. Beckman orders the team to complete the sale to gain access to Ahmad's accounts as part of their investigation. Unaware of the team's true intentions, Jack sets up the plan – Casey will pose as security, while he, Sarah and Chuck (who, as Lichtenstein, only speaks German)
