A clock maker / repairman buys a strange looking clock that will not run and becomes obsessed with getting it to work. When his hypochondriac, nagging wife tries to examine it she pricks her finger inside of it, saying (\"something BIT me.\") The clock starts up, and its beat is the sound of a human heart.

It also has a mysterious 13th number on it, and when the clock\'s strange chime rings on that number, everything freezes except for the clock maker. He becomes addicted to the 13th hour of extra time he\'s given and is finally crestfallen when the clock stops. (He doesn\'t put two and two together that the clock stopped at the very second his wife died.) Remembering how the clock started before, he sneaks into his doctor friends office, steals a vial of blood and pours it into the top of the clock (the \"brain or whatever it was\" he calls it), and the clock restarts. There\'s just one problem...people whose blood he uses mysterious die eventually...

(As I said, this episode is really an interesting study in addiction when you listen to it...)
