An investigation into the victims killed and secretly buried by the IRA during the Troubles in Northern Ireland.

One of the greatest poets of his generation, Norman MacCaig (1910-96) was also an expert fly-fisher. His favourite loch, the Loch of the Green Corrie, lies high up in the mountains of Assynt in the far north-west of Scotland. Fiddle maestro Aly Bain, Billy Connolly and award-winning poet and novelist Andrew Greig celebrate MacCaig in the centenary year of his birth with a journey from Edinburgh to Assynt and then the long climb to the Loch of the Green Corrie with its elusive trout.
