Matt Baker and Ellie Harrison are exploring Hampshire. Matt casts off at the opening of the trout fishing season on the River Itchen: a chalk stream which attracts anglers from all over the world. On the banks of the river, Ellie is on the look out for the wildlife that make this place home, but getting a glimpse requires some rather high tech equipment. Katie Knapman takes a trip down very different Hampshire river - the Hamble - to explore the history of sailing from traditional gigs to modern day yachts. Back on dry land, Jules Hudson finds how gun dog trainers keep their animals' senses sharp.
