Plot summary
During a diplomatic mission, Captain Picard is gravely wounded and transported directly to sickbay. As Dr. Crusher works frantically to revive him, Picard awakens to find himself in an otherworldly realm where he is greeted by the god-like alien Q. Q bluntly tells Picard that he is dead, explaining that a terrorist's weapon destroyed his artificial heart. Picard lost his natural heart as a young officer when he was stabbed during a bar brawl, an event he regrets. When Picard reflects that he would do things differently if he could relive that moment, Q sends him back in time to the day before the bar brawl, where he meets with fellow cadets Corey Zweller and Marta Batanides. They remark on his sudden personality change – no more devil-may-care attitude.
After being cheated by a Nausicaan in a bar game, Zweller plans revenge by rigging the next match. Picard talks him out of it, but the Nausicaans try to goad them into another game, which Picard prevents. When Zweller is provoked into attacking the Nausicaans, Picard holds him back, averting tragedy but humiliating his friend. The Nausicaans walk away laughing, and Zweller and Batanides leave in disgust.
Q returns Picard to the Enterprise in the present. To Picard's surprise, he is not the captain but rather a junior science officer who has led an unremarkable career. He consults Commander Riker and Counselor Troi, who explain that his aversion to risk means he has never distinguished himself.
Picard confronts Q, who tells him that although the fight with the Nausicaan was nearly fatal, it also gave him a sense of mortality and taught him that life was too precious to squander by playing it safe. Picard realizes that attempting to suppress and ignore his past indiscretions has resulted in losing a part of himself. He declares that he would rather die as captain of the Enterprise than live as a nobody. Q sends him back to the bar fight and events unfold as they did originally, with Picard stabbed through the heart and laughing as he collapses to the floor.
Picard awakens in sickbay, captain of the Enterprise again. As he recovers, he wonders whether his journey into the past was one of Q's illusions or merely a dream. Regardless, he is grateful for the insight the experience gave him.
