The final three recruits have been tested to their limits and beyond in their bid to come to grips with the spying game. With their training now complete, the trio must undertake a final confidential mission abroad, working against professionals. Without the support of their trainers and unsure if they can trust each other, they must complete their mission without being detected by their target or the local authorities. There is also a final twist in the tale, as the recruits are followed by a real professional, an ex-spy, who uses his professional expertise to trick them. Only one recruit will return from this mission as the perfect spy.
