The US Government uses Enhanced Interrogation Techniques to get information from prisoners. One such technique is to put the subject into a "Stress Position". These very physically challenging positions are held until the person is willing to divulge the information the interrogator is looking for.
Unfortunately Kate has no such information to offer up in exchange for release. Her torment proceeds until her captor is satisfied. For Kate that is well past her comfort zone.
Each position is harder than the last. First she's simply standing bent over. The next position has her ass filled with a locking mechanism which is attached to the ground and her hair up to the ring above her. The final position is a deep squat with her arms in strappado. Kate struggles through each position showing her toned body.
