Annabelle buys her daughter, Christie, a wind-up doll named "Talky Tina" in order to comfort her. When wound, the doll says, "My name is Talky Tina and I love you very much." Annabelle has recently remarried to an infertile man named Erich Streator. Frustrated by his inability to have his own children with Annabelle, Erich directs his hostility toward Christie (he also becomes upset with Annabelle for wasting money by purchasing the doll). Annabelle tries to persuade him that if he gives himself the chance, he will be able to love Christie.




When Erich is alone and he winds up the doll, it substitutes its catchphrase with antagonisms such as "I don't like you". At first, Erich blames the doll's manufacturer. However, when the doll begins engaging him in a more elaborate conversation, he comes to the conclusion that Annabelle is playing a trick to get back at him for his treatment of Christie. He places the doll in a trash can in the garage, but then receives a phone call and hears the doll's voice threatening to kill him. Checking the trash can, he finds it empty. He confronts Annabelle, but she pleads innocence. It occurs to Erich that since his wife was upstairs putting Christie to bed, she could not possibly have made the phone ring.




He runs upstairs to find the doll in bed with Christie. Erich takes the doll away against Christie's tearful protests and angrily corrects her when she addresses him as "Daddy". He attempts to destroy the doll using a vise, a blow torch and a circular saw, all to no effect; Annabelle attempts to intervene but Erich pushes her away. He then ties the doll in a burlap sack and returns it to the trash can, weighing the lid with bricks. Annabelle begins packing to leave, unable to tolerate his hostility and irrational behavior any longer. She says that Erich should see a psychiatrist. Erich begins to question whether the doll talking to him was just his imagination, and he offers to return it to Christie if Annabelle will stay. He takes the doll out of the trash and returns it to Christie.




Later that night, Erich is awakened by muffled noises. He tells Annabelle to stay in the bedroom, and leaves to investigate. Christie is in bed, but Tina is gone. Going down the stairs, he trips over Tina, who is lying on one of the treads, and falls, sustaining fatal injuries. Attracted by the noise, Annabelle finds Erich's body. Beside him is Tina, who opens her eyes and threatens Annabelle by saying, "My name is Talky Tina... and you'd better be nice to me!" Realizing that Erich was telling the truth, Annabelle drops the doll in shock.
