Ali a Bobby's tour takes them to northern France. First stop is a lake holding ornamental koi carp, where they have a competition to see who can catch the most colourful fish. Next, the boys travel to Sens, to a lake called Le Prunet, which holds carp to over 80lbs. The mission here is to catch a carp of 40lbs plus. Their tactical plan for day and night bites and works well, but will they bank a real biggun', or will they run out of steam first with little sleep and intense heat?
