I think you've managed to name everything I've enquired about so far, despite the very slight info I've been able to provide, so here's another. I'm pretty sure it was a one-off, on ITV, late seventies to early eighties, and concerned a young girl, ( I think she was supposed to be 13 or 14 though the actress who played the character was obviously older), and I'm pretty sure that she was either mixed race or black, who was taken into care or a young offenders institute or something, and I remember I was deeply engrossed in it until the the young girl was ordered to strip by a stern matron type and there she was on screen full frontal. I was watching with my mum and nearly died of embarassment! I think I made my excuses and went to bed at that point. Has anybody got even the faintest idea what I'm talking about?
