In a trio of chilling tales unified by the menacing presence of Boris Karloff's narration, the first story, "The Telephone," follows Rosy, a French call girl, who begins receiving threatening phone calls from an unseen stalker. As the calls escalate in their danger, Rosy fears that Frank, her former pimp whom she betrayed and sent to prison, is out for revenge. The tension builds as Rosy tries to reach out to her friend Mary for help, only to become more entangled in a web of fear, leaving her to wrestle with the reality of her past misdeeds and the ghost of a potentially deadly confrontation.

The second tale, "The Wurdalak," set in 19th-century Russia, ventures into the realm of vampires. When a nobleman stumbles upon a decapitated corpse with a knife plunged into its heart, he takes the weapon and continues his journey to a rural cottage. There, a family awaits the return of their father, who warned them that if he should return after ten days of hunting a notorious bandit, they should not let him in, as he could become a wurdalak—a vampire preying on his loved ones. When the father does return just at the ten-day mark, his family is thrown into a nightmarish struggle as they grapple with love, suspicion, and the haunting specter of the undead.
