The broken souls who attend the self-help seminar are all struggling with different issues, including addiction, anxiety, depression, and past traumas. The famous guru leading the retreat, Dr. Nathaniel Blackwood, promises to transform their lives through a series of unconventional and often extreme methods.
As the days progress, the participants are subjected to intense therapy sessions that push them to their limits. They are asked to reveal their deepest fears and regrets, and to confront the source of their pain. Some begin to make progress, but others become increasingly unsettled by the guru's methods.
Tensions come to a head when a member of the group is caught lying during a session and is subjected to the guru's latest experiment - a truth serum. The revelation of their darkest secrets leads to a violent confrontation, and the group begins to realize that Dr. Blackwood's motives may not be as altruistic as advertised.
As the retreat spirals out of control, the participants must decide whether to continue with the program or to try to escape. Some are ready to leave, but others are drawn in by the promise of a new life. In the end, they will need to confront their own demons and decide whether the trauma therapy has truly helped them heal - or whether it has only caused more damage.
