The teams land in Barcelona to take on the Vixen and the Menace, who have set a series of quiz questions that the teams must solve to navigate across the city and find Bradley Walsh at the finish line. Competition is fierce as teams do not want to finish last. If they do they face a head-to-head showdown with the Chasers. The final pair will need to beat them to join the other teams and head onto the next city, lose and it's the first flight home.
