The first half of the episode covers Yang Wen-li's childhood, and eventual admission to the Free Planets Alliance Officer Academy on Heinessen following the death of his father. The rest of the episode covers the events of the Imperial attack on El Facil, and Yang's leadership of the civilian evacuation that earned him the title, "Hero of El Facil."

On 19 September 788 UC, Yang Wen-li is promoted to Lieutenant for his efforts in evacuating the civilians of El Facil. Six hours after his promotion, he is promoted again to Lt Commander, making it effectively a double promotion. For the next few weeks, he is thrown into a flurry of events as many people from various sectors of society ranging from the media to his estranged maternal family try to capitalise on his new fame, which he comes to detest. Eventually in October while waiting for his new assignment and avoiding the limelight, Yang is assigned by Alex Cazerne to investigate the Tuesday Correspondence and ascertain the truth behind their allegation that the Free Planets Alliance war hero Bruce Ashbey was murdered.

Yang Wen-li reviews the history of the Year 730 Mafia.

Yang Wen-li reminisces about his days in the Free Planets Alliance Officer Academy spent with Jean Robert Lapp and Jessica Edwards. He later meets with Alfred Rosas to discuss about the latter's past with the Year 730 Mafia and specifically the circumstances surrounding Bruce Ashbey's death.

The history of the Second Battle of Tiamat is chronicled. In December 745 UC, the Free Planets Alliance and the Galactic Empire clashed in the Tiamat Starzone. The Alliance Fleet under the overall command of Admiral Bruce Ashbey is composed of fleets led by members of the famed Year 730 Mafia. There are however signs of internal dissension right before the battle, threatening the morale of the fleet. In contrast, the Imperial Fleet, under the overall command of Fleet Admiral Zieten, is in high spirits, albeit being rather single-minded in hunting down Ashbey. Nevertheless, the battle starts with the Alliance fleet quickly gaining an advantage by succeeding in destroying Vice Admiral Wilhelm von Mückenberger's fleet.

The history of the Second Battle of Tiamat continues to be chronicled. On 7 December 745 UC, having temporarily retreated and regrouped, the Alliance Fleet and the Imperial Fleet engages each other again. Worsening internal conflict amongst the Alliance fleet commanders does not appear to impair their command decisions in the front lines. However, as the battle progresses into a stalemate, the Alliance Fleet is in danger of being completely surrounded by the larger Imperial Fleet. Nevertheless, the Imperial plan fails when Bruce Ashbey, having foreseen this situation, reinforces the besieged Alliance Fleet at an opportune moment, throwing the Imperial encirclement into complete disarray.

Yang Wen-li attends the funeral of Alfred Rosas, and discusses the Year 730 Mafia with Alex Cazerne and Dusty Attemborough. Later, he reviews the fate of the Year 730 Mafia after the Second Battle of Tiamat. Before he can come up with any concrete conclusions however, he is notified of his new appointment in the planet Econia, which hosts a prisoner-of-war camp.

Yang Wen-li travels to his new post on the planet Econia in the Thanatos Starzone. There, he makes acquaintance with Fyodor Patrichev as well as a number of veterans from the Second Battle of Tiamat, including the oldest prisoner-of-war in the Econia Internment Camp, Christopf von Köfenhiller.

A prisoner named Presberg takes several Free Planets Alliance officers hostage: Yang Wen-li is ordered to substitute himself, along with Fyodor Patrichev, for the safe return of the hostages. Another prisoner, Christopf von Köfenhiller, also volunteers to be a hostage.

Captain Barnaby Costea orders the troops under his command to attack the rebelling prisoners, intending to kill both Yang Wen-li and Fyodor Patrichev in the crossfire as he fears they will expose his embezzlement of camp funds. With the help of Christopf von Köfenhiller, Yang, Patrichev and the rebelling prisoners are able to escape the compound. Presberg informs Yang that his rebellion had been staged and that Costea had promised him an early release back to the Galactic Empire if he played along. Yang and Patrichev break into the Econia Internment Camp's command centre and capture Costea. They then report the events that have transpired to the Thanatos Starzone military police.

Murai, an agent of the Free Planets Alliance military police in Thanatos Starzone, is dispatched to Econia to ascertain the situation. He holds interviews with everyone involved, even peripherally, in the incident. In the end, Barnaby Costea is placed under arrest to be court-martialed for embezzlement and for causing the deaths of those who died in the staged prisoner rebellion, whereas Fyodor Patrichev is given an unofficial reprimand. Alex Cazerne arranges for Yang to be transferred back to Heinessen, and Christopf von Köfenhiller is released from the Econia Internment Camp and granted Alliance citizenship, as well as a military pension befitting his former rank of Captain in the Imperial Fleet.

Yang Wen-li and Fyodor Patrichev, having received transfer orders out of Econia, accompany Christopf von Köfenhiller to Heinessen. During a layover on the planet Masszitt, Köfenhiller recounts his participation of the Second Battle of Tiamat and the circumstances that triggered his interest in investigating the connection between Martin Otto von Siegmeister, Christoph von Michaelsen and Bruce Ashbey. Soon after he finishes his tale, he dies in the spaceport terminal.
