The Ozernaya River winds serpentine-like through a remote corner of Kamchatka in Far East Russia. In one of the most intact eco-systems left in the Northern Pacific, rainbow trout eat mice for breakfast, and the salmon run in the hundreds of thousands. This bounty attracts two kinds of people; those who want to protect, and those who want to exploit. Rampant salmon poaching is big business on Kamchatka, and once the salmon are gone, entire eco-systems collapse. "At the End of a Rainbow" explores how fly fishing can help protect the wilderness, and celebrates the beauty and wonder of one of the most vibrant places on Earth.
