Hi there,
I watched some episodes on Sky One in the early 90's of a scifi-horror series. All I remember it kind of started on a spaceship where there was a big door or vault closed and for some reason people got hipnotized (?) and forced it to open. There was a blinding light and something got out... It did something to people - if I remember some nasty thing like a tentacle or something bursted out ffrom their chest and infected (?) other people.
Now after these years I got curious what this series was really about :-)
