Screen One - Tender Loving Care (with Dawn French) 1993

I remember this one off drama so well - never seen it since
Not available on dvd or anything?
Anyone else remember it and anyone know of any way to see it again??
Dawn French as a nurse murdering elderly patients and eventually murdering her co-worker in a very clever way!!
Can't really imagine bbc doing a drama like this anymore?
In fact one off dramas are quite rare nowadays aren't they?
Screen One and Screen Two seemed a good idea to me
