Four men set off for some white water rafting and a spot of illegal hunting in a 'wild' landscape of hills and a river that is due to be covered by damned water in the near future. (That's water held back by a large concrete edifice and not H2O from Hell).
The journey is planned over steins of beer and main instigator Lewis sells it to the other three as an opportunity to have a 'real' experience before 'the real estate people get hold of it and make it into one of their heavens.'
Lewis is someone who "tries by any means - weight lifting, diet, exercise, self-help manuals from taxidermy to modern art - to hold on to his body and mind and improve them, to rise above time.' The narrator, Ed, has accompanied him through many of these interests and admires him although he can see that he holds a type of death wish. He too seems concerned with the onset of middle age, and unsatisfied with his relatively successful city life and marriage.
