The U.S.S. Enterprise and crew are summoned to investigate strange occurrences aboard the starship U.S.S. Tsiolkovsky, which has been monitoring the collapse of a red-orange star.

Once aboard the troubled research vessel, the away team finds a ship littered with food, wine, discarded clothes, several frozen bodies and no survivors.

Unknowingly, Geordi energizes back aboard the U.S.S. Enterprise carrying a contagious, deadly contaminant that begins to infect the entire Starfleet crew, making them feel and act as if they were intoxicated and mentally unstable.

While Dr. Crusher searches for an antidote, chaos erupts when Wesley takes control of the ship.

Finally, Lieutenant Commander Data and Chief Engineer MacDougal, fighting the effects of the ailment, manage to get control of the ship. While Dr. Crusher administers the remedy to the mysterious contaminant, the crew, with Wesley's assistance, diverts the ship from further danger when a piece of the star's surface breaks off and heads directly toward the U.S.S. Enterprise. Captain Picard commends his crew for a job well done.
