Silent Retreat (2016)
Plot: Six employees of a high-pressure media company arrive at a remote mountain lodge for a weekend of team-building and professional development. Tensions are already high due to office rivalries and secrets, but the atmosphere turns deadly when one member of the group, Rita, suddenly vanishes. While searching for her, the co-workers discover that their retreat was formerly a private mental institution closed years ago following reports of horrific patient abuse. As they are picked off one by one, they realize a traumatized killer is stalking them, obsessed with the idea that "liars must be punished." The survivors must confront their own deceptions to survive a night of psychological and physical terror.
