Burn Notice
One player has to be the burned agent - the others are his past 'friends'. His objective is to get back into the Agency he was falsely burned from - till then he can't leave the local system (the primary world should be a Garden Hi Tech world).
For PCs to survive they have to take odd jobs using their skills and connections from their former careers helping clients, and avoid being killed by main PC's former enemies and allies, while avoiding entanglements with local authorities and yet still trying to help him clear his name and get back in with his former Agency.
