Ok, I'm remembering a show in the 80's about (I should say I think its about, my poor brain doesn't reach back that far with any measurable accuracy) a family that gets... transported(?) to another dimension(?) which seemed fairly earth-like but ruled by some sort of totalitarian state. The poor earth family would get hunted from town to town, I think, and I'm pretty sure there was some sort of recurring villain, a secret police type fellow in a uniform.
Anyone remember what I'm going on about, or is this a figment of my imagination?
