About this programme

4/8. Actor Robson Green heads to Canada to take on some of the country's most experienced fishermen, visiting the Fraser River Canyon in search of white sturgeon, the biggest freshwater fish in North America. He hopes to put his fly-fishing knowledge to good use during a trip to the Yukon and the remote Coghlan Lake, considered one of the top three fishing destinations in the world, before travelling to the Takhini River, where a lesson in what to do if confronted by a bear does little to reassure him.
