The trouble begins when the Enterprise plays host to a delegation of Ullians, a race of telepathic aliens. In addition to reading other people's memories, the Ullians also have the capacity to retrieve those memories. Before long, three of the crew members -- Troi, Riker, and Dr. Crusher -- lapse into inexplcable comas. Written by Pamela Gray, Jeri Taylor, Shari Goodhartz, and T. Michael Gray, "Violations" originally aired February 8, 1992. ~ Hal Erickson, Rovi
