Context: Brink (Sir Cedric Hardwicke) has recently taken Pud's (Bobs Watson) parents in an auto wreck. Brink later comes for Gramps (Lionel Barrymore). Believing Brink to be an ordinary stranger, the crotchety old Gramps orders Mr. Brink off the property. Pud comes out of the house and asks who the stranger was. Gramps is surprised and relieved that someone else could see the stranger; he was not merely a dream or apparition. Pud tells Gramps that when he does a good deed, he will be able to make a wish. Because his apples are constantly being stolen, Gramps wishes that anyone who climbs up his apple tree will have to stay there until he permits them to climb down. Pud inadvertently tests the wish when he has trouble coming down from the tree himself, becoming free only when Gramps says he can. Pud's busybody Aunt Demetria (Eily Malyon) has designs on Pud and the money left him by his parents. Gramps spends much time fending off her efforts to adopt the boy. Brink takes Granny Nellie (Beulah Bondi) in a peaceful death just after she finishes a bit of knitting. When Mr. Brink returns again for Gramps, the old man finally realizes who his visitor is. Determined not to leave Pud to Demetria, Gramps tricks Mr. Brink into climbing the apple tree. While stuck in the tree, he cannot take Gramps or anyone else. The only way anyone or anything can die is if they touch Mr. Brink or the apple tree. Demetria plots to have Gramps committed to a psychiatric hospital when he claims that Death is trapped in his apple tree. Gramps proves his story first by proving that his doctor, Dr. Evans (Henry Travers), can not even kill a fly they have captured. He offers further proof of his power by shooting Mr. Grimes (Nat Pendleton), the orderly who has come to take him to the asylum; Grimes lives when he should have died. Dr. Evans is now a believer, but he tries to convince Gramps to let Death down so people who are suffering can find release. Gramps refuses, so the doctor arranges for the local sheriff to commit Gramps while Pud is delivered to Demetria's custody. With the help of his housekeeper (Una Merkel), Gramps tricks both of them into believing they are scheduled to go with Mr. Brink when he comes down from the tree. They beg Gramps to convince Brink otherwise, and Demetria vows never to bother Gramps or Pud again. Gramps realizes that sooner or later he will have to let Brinks downDeath is an ultimately unavoidable part of life. He tries to say goodbye to Pud, who reacts angrily and tries to run away. Mr. Brink sees Pud in the yard and dares him to climb the tree. Pud gets over the fence Gramps has had built around the tree, but falls and is crippled for life. Distraught, Gramps lets Death down from the tree. He takes both Gramps and Pud, who find they can walk again. In the final scene, they walk together up a beautiful country lane and hear Granny Nellie calling to them from beyond a brilliant light.

Context: Rose Elliot (Irene Miracle), a poet living alone in New York City, discovers an ancient book called The Three Mothers. It tells of the existence of three evil sisters who rule the world with sorrow, tears, and darkness. The book, written by an architect named Varelli, reveals that the three dwell inside separate homes that had been specially designed and built for them by the architect in Rome, Freiburg, and New York. Rose suspects that she is living in one of the buildings and writes to her brother Mark (Leigh McCloskey), a music student in Rome, urging him to visit her. Using clues provided in Varelli's book as a guide, Rose searches the cellar of her building and discovers a hole in the floor which leads to a water-filled ballroom. After accidentally dropping her keys into the water, she enters the flooded room. Swimming under the surface, she sees a portrait bearing the words "Mater Tenebrarum" and is able to reclaim the keys. A putrid corpse suddenly rises from the depths, frightening her. She escapes, although a shadowy figure watches her leave the basement.In Rome, Mark attempts to read Rose's letter during class. He is distracted by the intense gaze of a beautiful student (Ania Pieroni). When the class ends she leaves suddenly; Mark follows, leaving the letter behind. His friend Sara (Eleonora Giorgi) picks up the letter, and eventually reads it. Horrified by the letter's contents, she takes a taxi to a library and locates a copy of The Three Mothers. While looking for an exit, Sara is attacked by a monstrous figure who recognizes the book. She throws the book to the ground and escapes. Later that night, she seeks the company of a neighbor named Carlo (Gabriele Lavia) and both are stabbed to death by a gloved killer. Mark discovers the bodies and two torn fragments from Rose's letter. After the police arrive, he walks out of Sara's apartment and sees a taxi slowly driving by.

Cut off, Rose sees two shadowy figures preparing to enter her apartment. She leaves through a back door, but is followed. In a decrepit room, she is grabbed from behind by a clawed assailant and brutally murdered.Upon arriving in New York, Mark meets some of the residents of Rose's building, including a nurse (Veronica Lazar) who is caring for the elderly Professor Arnold (Feodor Chaliapin, Jr.), a wheelchair-bound mute. Mark learns from the sickly Countess Elise (Daria Nicolodi) that Rose has disappeared. Elise explains how Rose had been acting strangely.

However, the man provides no information. That night, Kazanian drowns several cats in a Central Park pond and accidentally falls into the water. Hundreds of rats from a nearby drain crawl all over him, gnawing his flesh. A hot dog vendor hears Kazanian's cries and rushes over. The man kills Kazanian with a knife.Carol, the caretaker, discovers the horribly mutilated corpse of Elise's butler (Leopoldo Mastelloni) in the Countess' apartment.
