The story beautifully illustrates the intergenerational bond between a grandfather and grandson through the lens of this wonderful outdoor tradition. A grandfather, Papa, takes his 9-year-old grandson, Rivers, on his first fly fishing trip. Feel the emotions as the pair wades through a cold mountain stream in search of trout. The grandfather shares his knowledge, love for nature, and family values with his young grandson as the boy loses his first fish but finally catches his "river monster."
