Setra, a great sea trout, enters the Tors river estuary from the sea in spring. He is drawn up the waterway by the spawning urge to mate in the moorland headwaters in winter. An old fisherman, Pengelly, lives alone above the river in a granite cottage; he hopes to catch Setra on this up-river journey but exhausts himself in the pursuit.
There are stories of trout, salmon, pike and more!
