Ali and Bobby head to southern France for the final leg of the tour with a diver and underwater cameras in tow, to a fishing holiday complex called Iktus. The first mission is to catch a giant sturgeon. They can be tricky to catch, but the boys are armed with their invaluable underwater intel. Next, onto the main lake that holds monster PB-busting carp to over 80lbs. The dream here is to catch a French PB and capture all the action on the underwater cameras too.
