R. L. Stine’s The Haunting Hour Season 1 Episode 16

The two meanest girls at school, Stephanie and Taylor, prank call the next door neighbor, Mrs. Biazevich. Mrs. Biazevich warns them to be nice girls and dies the next day. Stephanie starts receiving text messages telling her to be a nice girl and then finds out that the calls are coming from Mrs. Biazevich’s phone. The girls figure out that her spirit is haunting them. Mrs. Biazevich’s spirit visits Stephanie and Taylor and sees that Stephanie is still very mean. Mrs. Biazevich lets Taylor go because she can see good in her heart but traps Stephanie in a video in her cellphone and sends it to her granddaughter, Adriana, the girl Stephanie and Taylor made fun of at school. Adriana sneers at Stephanie trapped in the video and deletes the video, effectively erasing Stephanie from existence. Stephanie is gone and cannot come back, because she is technically dead.
