Savage Street (aka Man in the Shadows) - S1.E6

Robin goes to Paris to try to find two highly insured emeralds belonging to Caroline Agoura, which ostensibly went overboard with her late husband, Paul. By working with Tou Tou, a clumsy Parisian second-story man, Robin learns that Agoura is not dead, is a vague but notorious smuggler, who uses the emeralds as collateral for his deals.
