While answering a distress call from a scientific station in a remote part of the glaxy, the U.S.S. Enterprise™ becomes infected with a mysterious alien life form which feeds on and transforms inorganic materials.

The Starship begins to gradually disintegrate, and Starfleet is forced to order its evacuation and destruction to prevent the dangerous infection form spreading throughout the galaxy. It's the end of an era for Captain Picard and his crew, who are scheduled for transfers that will split them up among different Starfleet vessels.
