Murderous Trance (also titled The Guardian Angel)[1] is a 2018 psychological thriller film written and directed by Arto Halonen and starring Pilou Asbæk, Josh Lucas, Rade Šerbedžija, Cyron Melville and Sara Soulié.

[6] During the film's premiere in Finland and Denmark, it provoked a lot of discussion in the media among psychiatrists about the possibility to hypnotize people to act against their own morals, and the specialists unanimously confirmed it plausible.

In the article Hannu Lauerma, an associate professor of psychiatry at the University of Turku, stated, ‘In a continuous long-term indirect influence by suggestion you can make things seem other than what they actually are.

[9] Arto Halonen was one of the first ones who were able to find the hypnosis murderer Palle Hardrup [da; fi], who had changed his name after having been released from prison in 1967.

Absorbed in the criminal investigation, Olsen does not realize that the mysterious Nielsen has secretly befriended his young wife (Sara Soulié).
