This is a Halloween tradition for me, ever since it first aired when I was 10 in 1990. AKA the cursed Quantum Leap episode. Very creepy and appropriately spooky. Hulu Plus is now streaming all Quantum Leap episodes. If you have a chance, watch it late at night and enjoy.
Sam leaps into Joshua Ray, a horror novelist on Halloween. Residing in a church haunted house scheduled to open that day, Sam starts noticing creepy happenings and odd murders Al did not predict. It is a very well written episode with scary diabolic twists. Enjoy.
