Saw this a few weeks ago on Virgin One afternoon TNG reruns. It's a real cracker of an episode.
On a side note, I wasn't aware that the BBC have ever shown The High Ground
. It was banned by the BBC all through the 90's, and as far as I know, the BBC haven't had the rights to show any TNG other than seasons 6 and 7 for a number of years. They occasionally stick a double bill on about 1am on a Friday night/Sat morning.
Gone are the good old days of BBC2 on a Wednesday evening at 6pm. But to be honest, the copies of TNG which the BBC have are such poor quality, I'd rather watch them on DVD.
