California has one of the most diverse populations of trout in the world, and in this film a group of adventurous anglers undertake a ten-day treck into the state's High Sierra in search of the famous golden trout - fish which have survived the onslaughts of the Gold Rush, and sheep and cattle farming's ravaging of the landscape and riverbanks. The guys explore previously unfished lakes and watersheds, and catch some remarkable hybrid trout, golden trout, camp in an old mining camp and meet some of the characters of the High Sierra.
