iStalker (2021)

A girl posts a social media video of her donating money to a homeless man but takes the money back when the cameras are off. A recurring event for her. A masked man nearby notices. She later basks in her social media clout at a bus stop when she receives an unusual series of messages and realizes she's being stalked. Her phone dies and she runs home. At home, she notices the messages she was sent earlier were sent from her house. She's been followed home. She hides in her closet until she feels the coast is clear and takes off for the front door. She is then knocked unconscious, and tied to a chair. A masked man gets his retribution on her by exposing her for who she is on a live broadcast.
