Martha and Finn's marriage is hanging by a thread.

Martha, crippled by paralyzing climate anxiety, finds herself at odds with Finn, who steadfastly refuses to confront the demons of his past. In a desperate attempt to repair their relationship, they join a group of privileged tourists on a pilgrimage to The Salt Centre, a mysterious retreat nestled deep within the Bolivian salt flats. United by a shared quest for spiritual enlightenment, the group embark on a journey guided by an elusive shaman.

As a series of salt ceremonies unfold, hallucinogenic episodes force each of them to confront their own versions of reality. When the final ceremony descends into a nightmare, Martha and Finn are met with an ultimatum. Forced to grapple with the moral implications of their trip they must ask themselves: are some wounds too deep to heal?
