A series of programmes made specially for audiences in the BBC regions and now seen for the first time countrywide.

Tonight, from BBC Scotland, the first of two programmes from the oil world of the North Sea.

Current Account joins the divers who are operating in the dangerous new frontiers of technology. They have to work at depths down to 600 feet to get the oil ashore and provide Britain with a vital economic lifeline.

John Milne reports on the kind of men who take on this dangerous job, the training they are given, the risks they face and the sort of lives they lead.
