After neutralizing the immediate threats posed by the rogue Section 31 agent's temporal anchors, Commodore Janeway and Admiral Townsend return to Starbase 113, their home base, to regroup and investigate further. Intelligence suggests that Section 31's rogue elements have deeply infiltrated Federation affairs, with multiple agents now actively working to destabilize key operations within Starfleet.

As the crew settles back into Starbase 113, new evidence comes to light: one of the rogue agents has been operating from within the base itself. Suspicion falls on key personnel stationed at the starbase, and Janeway and Townsend must discreetly investigate without alerting the saboteur, who could be watching their every move.

Complicating matters further, Starbase 113 is preparing to host high-level peace talks between the Federation and the Romulan Republic. These talks are crucial for maintaining stability in the region, and any disruption could reignite tensions, potentially leading to conflict. Knowing that the rogue Section 31 agents thrive in chaos, Janeway and Townsend suspect that the talks are the perfect target for their next act of sabotage.

As the USS Halo and USS Voyager crews work covertly to identify the rogue agents within Starbase 113, the peace conference begins. Tensions run high, as both Romulan and Federation delegates arrive with a history of mistrust. The base is put on high alert, with extra security measures, but the crew knows that the threat could already be inside the heart of their home.

The investigation leads the crew down a winding path of hidden communications, intercepted messages, and cryptic encounters with Romulan operatives. Janeway and Townsend must navigate the complex political landscape, balancing diplomacy with their covert mission to stop Section 31 from sabotaging the peace talks.

During the investigation, evidence emerges that not only is there a rogue Section 31 agent onboard, but multiple agents are spread throughout the diplomatic attendees, disguised as Federation personnel. With each passing moment, the threat grows more imminent, and Starbase 113 is at risk of becoming ground zero for a catastrophic event that could destabilize the entire quadrant.

Just as the talks near their climax, an explosion rocks the lower levels of Starbase 113. Security forces scramble to contain the damage while the Halo and Voyager teams race against time to stop the rogue agents from unleashing further chaos. The situation spirals out of control as Romulan officials begin to suspect Federation sabotage, and tensions rise to the breaking point.

In a daring final act, Janeway and Townsend lead a strike team into the heart of the starbase to capture the rogue Section 31 agents before they can carry out their final phase of sabotage—disabling the base's primary defensive systems and leaving it vulnerable to Romulan retaliation. As the crew works to stop the agents, they uncover a chilling revelation: Starbase 113 was not just a target, but a strategic hub for Section 31's covert operations, hidden right under their noses.
