1 - 4: 1280 meter

Jens Møller gets assistance with the search. Swedish cadaver dogs that can locate bodies more than 20 metres below sea level are brought in. Although the dogs mark the areas quite accurately, the divers don't find anything. There is a question over whether the dogs can be used at all. Then Jens Møller hears from an oceanographer who offers new insight.
