I remember a serial-type of show from the late 70’s/early 80’s (I was born in 73). It would have aired Sunday nights, somewhere around 8-9pm (eastern).
From what I remember (and I only remember one episode), the host was discussing superheroes. And it cut to an automotive garage/gas station, where a female superhero has been strapped to one of the automotive lifts. Then, back to the host, who starts explaining something about how superheroes can get out of traps like this.
I THINK the show aired on NBC, but I could be mistaken on that. I CAN say that it was a network show, as we didn’t have cable back then.
