Five days before D-Day, the day of the last voyage of the Order of Sirius, a sect nestled in the Vaudoise Alps, Switzerland. Five days during which a community of 48 people, women, men, children, fed with esotericism and guided by a narcissistic guru, will test their faith and be deprived of their identity. Five days in which every gesture will be the last. Sirius is inspired by the massacre of the Order of the Solar Temple in 1994 in western Switzerland.
Unfortunately the movie Sirius is not yet available on HBO Max.
