They describe the spy game as a wilderness of mirrors because you can never be sure whether you're in control or under control. When they say you're back for one last job, it's because it's the last job you'll be alive to do. Coming in from out of the cold is usually just the prelude to moving from the frying-pan and into the fire.

As burned agents, you're being brought back in from the cold for one last job and all you need to do is find the traitor in an organisation that thinks you already were one.

This is a non-procedural game of truth and lies using the Mountain Witch system. A high level of player creative input is required, and all I can guarantee is that not everyone is going to make it out alive.
