It's... really not anything like a soap opera, honestly. It was on at the same time as Classic Doctor Who was, and was basically a great little show about time, consequences, and grown men being attacked by floating pillows. There's a rather good TVtropes page over here.
It was basically about a mysterious man and woman (named Sapphire and Steel, respectively) who showed up whenever Time began to break through into the real world, and basically beat it back by glaring at it and occasionally freezing it using Steel's weird powers. It's... surprisingly hard to describe, actually. I really like it for some reason.
