LFO

LFO is a 2013 Swedish science fiction film directed and written by Antonio Tublén about a man who realizes that he can hypnotize with sound. He starts experimenting on his neighbors, where the abuse of power takes over and, eventually, severe consequences for mankind are at stake. Plot Robert Nord, an awkward man, spends most of his time playing with his synthesizers in his basement. After he has an argument with his wife Clara, whom he suspects is cheating on him, he returns to the basement again, to her annoyance. There, over the Internet, he discusses with several of his friends his belief that he has what he calls a "sound allergy" to the music that his wife enjoys. He proposes that a certain frequency could act as the opposite of this allergy and give him the peace that he desires. With the help of Sinus-San, one of his friends from the Internet, he makes a breakthrough, though he hides the extent of his success. When Simon and Linn move next door to him, he resolves to experiment on them over the objections of his wife. Robert invites over his new neighbors. Before he leaves to get the coffee, he casually mentions that his family was killed in a car crash. Uncomfortable with the awkwardness of the conversation, Simon tells Clara that he intends to leave. However, when Robert returns, he plays a hypnotic frequency that compels them to obey his commands. He orders Simon to perform menial tasks and Linn to have sex with him. When Clara calls him pathetic, he defends his actions as being necessary to test the extent of his control. Eventually, it is revealed that Clara and his son, Sebastian, died when Robert sabotaged the family car. Clara chides him to take his antipsychotic medicine, pointing out that she is a hallucination, but Robert refuses. Instead, he forces Simon and Linn to take the place of his dead family members. After several weeks of servitude at his house, his neighbors are reported missing, and the police show up at Robert's house to ask him if he has seen them. Robert panics and hypnotizes the police into leaving his house. Unsatisfied with his fake family, he releases Simon and Linn, though he monitors their life using security devices. When Linn accidentally discovers through the security device that Simon has been cheating on her, Robert hypnotizes them into accepting him as their marriage counselor.
