Spies (C4, 9pm)

As we reach the end of the series, six trainees remain on the course, but only four can make it through to the final, solo test. This last challenge, which involves a mission in Marrakech, has been designed to recreate the conditions a genuine intelligence officer might face in hostile conditions. On arrival, the trainees must hand their passports to an unknown contact and use their alias documents to check into a hotel, all while acting 'normally'. However, unbeknownst to them, they can't even relax behind closed doors as their hotel rooms have been rigged with cameras to observe how they deal with the pressure. One candidate is already struggling to keep it together and things are only about to get worse as the trainees are 'arrested' and subjected to a hostile interview under extreme conditions. By this point only three remain, but who will emerge as the best potential spy?
