A murder and theft at Washington State University was flagged by automated monitoring systems set up by Delta Green. A team of agents is hastily assembled and sent to the murder scene as quickly as possible. The victim was a geologist and several samples of an unusual nature were stolen from the lab. Unfortunately, the true nature of these samples is unknown, only that they refer to an earlier Delta Green case. The team must not only find the killer but learn the true nature of the samples and recover them if possible. The investigation will lead them to dark places, facing even darker opponents.
