Limoux is a city in France.
Onboard the Bus, Agents Fitz and Simmons discover that the design of the weapon they retrieved on Jamaica is Chitauri-inspired but augmented with Overkill tech. Skye is able to hack the weapon's code and track its origin to a remote town in France. The Bus flies to the town of Limoux where the agents find themselves in the middle of the Tour de France. After locating the house and entering, the team is ambushed and Leo Fitz is captured and taken to Antarctica.
