The London Assignment

Many years after World War II, Russia's and France's spy agencies have agreed to form an alliance.
In London, two spies from the two agencies are forced to go on a mission together to hunt down a double agent fugitive, suspected to be working for the nefarious organisation, Parasiti. Soon enough, a bored detective decides to tag along as well, and together, they work "together" with "great teamwork" to complete their mission.
