It is 1968. DELTA GREEN is a top secret program within the US national security apparatus, dedicated to investigating and eliminating the Unnatural, – whatever the cost. The Agents are dispatched to a small town in New York state to investigate a pair of deaths. One deliberate, one seemingly a tragic accident, but both victims linked to the commune of devotees of psychology professor turned guru, Dr. Weyland Weber. Can the Agents discover what’s going on before someone opens a door that should remain closed?
