Wildlife cameraman Gordon Buchanan has come home to the island of Mull. He is keen to show off his homeland, in particular its wildlife. With his film camera by his side, he knows there are lots of animals on the island, but with only one day to find and film them, he could be pushed to deliver. His target for the day is a sea eagle - a very rare inhabitant of the island. He knows of a nest site where he should be guaranteed at least a glimpse of one of these magnificent birds. Along the way he is going to keep his eyes peeled for all sorts of other wildlife, including otters.

A look at ospreys, which travel thousands of miles from Africa to nest in the forests and hills of Scotland, fishing with their talons for trout in lochs. Plus pine martens, nocturnal hunters that are rarely seen.
