The I.B. are confronted by a case of 'the worst kind of smuggling'. Campbell puts Ross McInnes on the trail of the client concerned. Ross traces him as far as the Inner Hebrides but arrives too late. It seems he cannot pursue the case any further - it's a dead end. He returns to report his failure to a furious Campbell.
