When Lwaxana Troi drinks from a telepathic firehose, it gives her a wicked headache before putting her into a coma. But when Deanna Troi's investigation results in the discovery of a dark family secret, she must find a way to escape the prison constructed within her mother's mind. What is the easiest stitch? How do you comb your hair around temple loaf? Who does the gardening in the arboretum? It’s the episode that doesn’t have as many good ideas as the number of shows we have to do.
