Hannah has been running from her demons ever since she emerged from a harrowing wilderness trip without her fiancé. No one knows exactly what happened the day Ben died, and Hannah would like to keep it that way...even if his ghost still haunts her with vivid waking nightmares that are ruining her life. So when her friend group gets an exclusive invitation to a restorative spiritual retreat in Joshua Tree, Hannah reluctantly agrees in search of a fresh start. Despite her skepticism of the strange Guru Pax and his belief in the supernatural world, Hannah soon finds healing through all the yoga, sound baths and hot springs offered at the tech-free haven. But this peaceful journey of self-discovery quickly descends into a violent fight for self-preservation when a mysterious killer starts picking off retreat attendees in increasingly gruesome ways.
