A more recent radio show, i think from the late seventies.
"Night Fall" is a Canadian radio show that lasted for about a 100 episodes and is probably my second favorite series of all time. The shows tended to be a little weirder and stayed pretty clear of crime-drama territory, instead focusing on "Twilight-Zone"-esque scenarios. There are many favorites from this series but I find this one one of the most unsettling.
The plot concerns an actress who also works nights in a 24-hour laundry. She notices a very strange man enter one night, and then disappear- and then discovers human flesh in the washing machine. Its one of those "WTF" plots that "NightFall" seems so fond of, and its actually unsettling besides. Download it here.
