Howard has been chosen to work on the Defense Department's Laser Equip Surveillance Satellite project. He needs security clearance to work on the project which means the FBI will be interviewing each of Sheldon, Leonard and Raj. The interviews conducted by Special Agent Page, who is a beautiful young woman, don't go quite as each would hope. Because Agent Page is a woman, Raj can't speak to her until he gets drunk, and still then he believes her sole goal is to deport him back to India. Woman hungry Leonard decides to try his new confident persona to pick her up, which has unintended consequences. And Sheldon wants to speak more about his past encounter with the FBI than about Howard. Amidst these innocent topics of conversation, Sheldon inadvertently mentions the time when Howard crashed the Mars Rover when he was trying to impress a woman without security clearance. When Howard learns he didn't pass the security clearance, Leonard and Raj believe it is their fault, but Sheldon makes no mentions of his interview gaffe. After guilt gets the better of him, Sheldon confesses, but Howard won't accept his apology. Is there anything Sheldon can do to get back into Howard's good graces?
