Deirdre O’Kane went to Loretto Rathfarnham, an all-girls boarding school. In Class Clowns, Deirdre’s mates and former teachers talk about her time in what was a pretty enclosed world. We see an emotional reunion with Deirdre and two of the nuns and hear the truth behind The Great Loretto Rathfarnham Cigarette Scandal of 1985, or smoke-gate as it came to be known.
