Iraida and Taisia are secrets agents who have been caught by the CIA and are being subjected to questioning. Both women are restrained and placed in the stocks. The lead interrogator from the CIA comes in and, after refusing to answer his questions, he begins his "convincing" method to get the answers he needs. Both women are subjected to tickling and trying to hold out without giving away the information, however, Iraida turns on her partner and divulges some information to the interrogator. Iraida, however, gave only partial information, so the interrogator gave her a choice - she could either continue to be subject to the ticking torment, along with Taisia, or she can turn on Taisia and administer a new interrogation method the CIA had been experimenting with.
