This Is Not Georgia (2020)

Thea is a 30-year-old American with a remote job that allows her to stay detached from any place or person; her only connection back home is a reluctant one with her delusional younger brother, Nick, who calls her constantly about the latest predictions of Sophie Proprischin, a famous Russian astrologist. One day, while passing through country of Georgia, Thea is informed by her estranged father that Nick will soon be committed into a mental asylum for the rest of his life. Before she flies out, Thea notices a poster advertising Sophia Proprischin's astrology seminar in Tbilisi and takes it as a sign-she extends her stay and invites Nick to visit her in his last days before being unknowingly committed to the mental asylum. However, the Nick's delusions follow him to Tbilisi and soon it spreads to Thea who begins to question her own reality.
