Thomas Mosgaard is a biologist, and he has a very deep knowledge regarding the behaviour of the seatrout and its holding spots. He has great experience catching seatrout in rivers, and we tag along as he fishes a number of smaller rivers in Jutland. Thomas especially puts emphasis on how to catch seatrout during the day hours – but we are invited along for some evening- and night fishing too. We fish up and down the rivers while Thomas tells us about fishing techniques and the holding spots that we come across. The film is about fishing spoons, spinners and wobblers – and how to fish them most effectively. We see a lot of dramatic and hectic fights with beautiful seatrout – and we are there when Thomas catches a strong salmon. It is a film filled with great tips and facts, intense fights and beautiful scenery along the rivers.
