Smile (2022)

After witnessing a deeply disturbing incident involving a patient, a psychiatrist starts experiencing strange and terrifying events that no one else seems to notice. People around her begin to act unnaturally, often wearing unsettling, forced smiles, and she becomes convinced that something sinister is following her. As her sense of reality slips, she struggles to find answers and uncovers a pattern linking her situation to others who suffered the same fate. The more she digs, the more isolated she feels, with her friends and colleagues doubting her sanity. Racing against time, she tries to figure out what's really happening and how to break the cycle before it destroys her too. The story leans hard into psychological horror, with a focus on paranoia, trauma, and the terrifying feeling that something horrible is lurking just out of sight.
