The Living Dead at Manchester Morgue (aka Let Sleeping Corpses Lie)

"A strange twist of fate brings two young travelers, George (Ray Lovelock, The Cassandra Crossing) and Edna (Christine Galbo, The House That Screamed), to a small town where an experimental agricultural machine may be bringing the dead back to life! As zombies infest the area and attack the living, a bullheaded detective (Academy Award® nominee Arthur Kennedy, Peyton Place) thinks the couple are Satanists responsible for the local killings. George and Edna have to fight for their lives, and prove their innocence, as they try and stop the impending zombie apocalypse!
