An interesting look back to the 70s when cryogenic freezing of people was thought to be the next big thing.  I'd think it's probably still around today, but I do wonder how extensive it is being used.  Of course as far as I know no one (or animal) has been successfully been brought back to life after being frozen, but still an interesting idea.  In this episode there is also the question of whether there really was a supernatural element or just insanity.

Overall it was a good listen.
