The Patrician's Birthday and a Chase
The story begins on the eve of the Glorious Revolution, the 30th anniversary of the day Commander Sam Vimes almost died. On Lord Vetinari's birthday, Vimes relentlessly pursues Carcer, a murderer and former Unmentionable, through Ankh-Morpork's streets. Carcer, responsible for several Watchmen's deaths, is brutally efficient. The chase ends at Unseen University, where Carcer tries to escape using a magical artifact. The struggle with Vimes causes a powerful magical discharge, tearing a hole in reality and sending both Vimes and Carcer through time.
Arrival in the Past
Vimes awakens in the past, on May 25th, 1968 (Ankh-Morpork calendar), the day the Glorious Revolution starts. He quickly realizes he is thirty years in the past, when he was a young recruit to the Night Watch. Disoriented but practical, Vimes sees the murder of Sergeant-at-Arms John Keel, his mentor from that time. To prevent a paradox and keep the timeline, Vimes must assume Keel's identity, using the 'Sergeant-at-Arms' sash he finds. This puts him directly in the city's revolutionary fervor, with the added pressure of knowing his younger self is also there.
Assuming Keel's Role and Shaping the Young Watchmen
As Sergeant-at-Arms John Keel, Vimes immediately takes charge of the Night Watch at Treacle Mine Road. He meets his younger, naive self, Corporal Vimes, along with other future Watch members like Nobby Nobbs and Fred Colon. Recognizing the period's historical importance, Vimes begins to teach his past colleagues policing wisdom and a sense of duty. He instructs them on proper investigation, evidence collection, and protecting the innocent, regardless of their social standing or revolutionary alignment. He also subtly guides his younger self, instilling the principles that will define Commander Vimes in the future, all while dealing with the city's rising tensions.
Carcer's Destructive Influence
Meanwhile, Carcer, also in the past, quickly adapts to the chaos. He uses his psychopathic tendencies and tactical skill to infiltrate and manipulate various revolutionary factions. He incites violence, plants false evidence, and creates distrust between revolutionaries and the existing authorities, the Unmentionables. Carcer's actions are driven by a desire for power and chaos, and he enjoys shaping history in a more brutal way. His presence worsens the already unstable situation, turning discontent into bloody conflict, creating a more dangerous past for Vimes.
The Barricades Rise
The discontent in Ankh-Morpork finally erupts into full revolution. Barricades go up across the city, dividing districts and creating zones for various revolutionary factions. The Palace Guard and the Unmentionables, representing the Patrician's rule, use brutal suppression tactics, causing more civilian casualties. The Night Watch, under 'Keel's' guidance, finds itself in a difficult position, trying to keep order and protect the innocent amid the rising violence. Vimes, as Keel, struggles to uphold the law and prevent more bloodshed, knowing the historical outcome of these events and trying to lessen the suffering.
Confronting the Unmentionables
Vimes, as Sergeant Keel, opposes the brutal and corrupt Unmentionables, the Patrician's secret police. He sees their atrocities and, using his future knowledge and resolve, protects citizens from their arbitrary violence. This defiance puts him in direct conflict with figures like the sadistic Reg Shoe and other Unmentionables. His actions inspire the younger Watchmen and earn him the respect of common people, who see him as a symbol of justice in a time of tyranny. This defiance also sets the stage for the confrontation that will decide the revolution's outcome.
The Truth About the Revolution
As 'Keel,' Vimes looks closer at the revolution's workings, realizing the 'Glorious Revolution' he remembers is not entirely as it seems. He finds evidence of manipulation and opportunism, particularly by figures like the lawyer, Roberts, who exploit people's grievances for their own gain. Vimes learns that the revolution was not a clean uprising but a complex, messy event with many shades of grey, and that history's 'heroes' were often flawed. This revelation challenges his understanding of his own past and the foundation of modern Ankh-Morpork.
The Battle of Cable Street
The revolution's climax sees 'Keel' leading a small group of Night Watchmen and civilian volunteers in a stand at Cable Street. They face overwhelming odds against the Unmentionables and the Palace Guard, who want to crush the rebellion. Vimes, using his future experience and tactical skill, organizes a defense, prioritizing the protection of innocent lives over any political agenda. This battle shapes the young Watchmen into true officers and shows the power of principled policing even against tyranny.
Confronting Carcer and the Time Paradox
During the revolution's chaos, Vimes, as 'Keel,' finally confronts Carcer. Their encounter is brutal and personal, with Vimes knowing he must eliminate Carcer to prevent him from changing history and to ensure his own future. The fight is intense, ending in Carcer's defeat and implied death by 'Keel's' hands, fulfilling the historical record. This confrontation is important for the timeline and for Vimes's emotional journey, as he deals with the morality of his actions and the need to ensure the past unfolds as it should, even if it means personal sacrifice.
The Patrician's Fall and the New Order
After the revolution, the tyrannical Patrician, Lord Winder, is overthrown, leading to instability before Lord Vetinari's eventual rise. 'Keel' plays a subtle but important role in this transition, ensuring that key figures and events match the history Vimes knows. While the revolution does not immediately bring the stable Ankh-Morpork of his time, Vimes ensures the groundwork for future progress and a more just society is laid. He observes the immediate aftermath, knowing his mission to preserve the timeline is almost complete.
A Final Goodbye and Return
With historical events secured, Vimes, as 'Keel,' has a final, emotional meeting with his younger self, Corporal Vimes. He offers wisdom and encouragement, subtly shaping the young officer's destiny and reinforcing the values that will define the future Commander. This interaction is a powerful moment of self-reflection and mentorship. Soon after, the magical anomaly that brought him to the past reactivates, pulling him back to his own time. He leaves the past knowing he has done his duty, preserving the timeline and ensuring the Ankh-Morpork he knows.
Back to the Present
Vimes returns to the present, reappearing on the rooftop of Unseen University. He faces Carcer, who has also returned, disoriented and weakened by the temporal journey. The past has deeply affected Vimes; he is now more resolute, his understanding of justice and policing deepened by living through the events that shaped his city. The chase continues, but Vimes is no longer just pursuing a killer; he is completing a cycle, bringing the full weight of his past and present experience to bear on his enemy. He apprehends Carcer, bringing him to justice in his own time.
