Murderbot rents Naja a mobility-assistance device, and the group restocks food before heading toward a transport junction. The station is heavily guarded, but checking local feeds, Murderbot discovers the alerts are for rogue SecUnits rather than B-E fugitives. When it suggests that the humans continue without it, all three refuse—Naja grabs its arm, and Sofi takes its free hand. Murderbot calculates the risks and continues forward. It feeds a guard’s scanner false readings, and Farai has Sofi talk animatedly about her favorite show, Honor Princess Detective, to help the group appear ordinary.

Murderbot notices minor security alerts that are beginning to form a directional pattern pointing toward a fast-approaching entity. A rogue SecUnit—not a B-E model—drops from an overhead walkway onto the platform. To prevent guards from firing into the crowd, Murderbot issues an unauthorized hold-fire command through the local security system. The rogue unit pings Murderbot and attaches a packet that Murderbot recognizes as its own governor module hack code, now apparently spreading among units on the torus. Murderbot sends the SecUnit a warning to leave along with a packet of basic survival codes, and the rogue unit flees. In the ensuing chaos, the group boards the arriving transport.

Heavy security throughout the subsequent zones makes their original route unusable. After disembarking at a large hydroponics station, Murderbot briefly considers deceiving the group and taking them straight to the shuttle, abandoning Leonide’s family, but it drops the plan, unwilling to make them hate it and aware that Farai is already tracking their location on the map. Naja proposes using the zone’s “flyers” (tourist vehicles) to travel through the torus’s inner air corridor; Farai adds that she and Naja are both licensed pilots. Murderbot agrees to try the plan.

To reach the flyers, the group boards transparent bubble vehicles that crawl up the hydroponic scaffold towers. Murderbot hacks the boarding system and erases the record, prompting Farai to ask sharply whether it could have been doing that all along. The extreme height unsettles Sofi. When they arrive, the attraction is closed for seven hours due to a sporting event. Murderbot views the closure as an advantage—no witnesses—and takes control of local systems to prep a small, brightly colored tourist flyer. Sofi is delighted.

Farai takes the pilot seat with Naja as co-pilot; Murderbot disables the flyer’s tracers and airspace restrictions. At the zone’s upper boundary, a warning buoy cautions that they are entering unaffiliated territory with inadequate security. The group proceeds.

Inside the corridor, they discover that one wall is a transparent barrier looking out onto the planet at the torus’s center. The planet is a ruin, mined so extensively that its surface is colorless, gouged, and visibly fractured, with no remaining atmosphere. Sofi asks who would do such a thing; Naja says flatly that corporates did. The flight stabilizes on a navigational beacon, and Murderbot begins watching Sanctuary Moon.

Later, with Sofi asleep against its shoulder, Murderbot’s threat assessment alerts it to a larger aircraft that is matching their speed. The craft hails them with a false claim of responding to a distress signal, then clamps a cargo-lifting field onto their flyer and lowers a boarding pod. Murderbot identifies the setup as a robbery and instructs Farai to cut the engines. Naja demands a weapon; Farai refuses. Murderbot struggles to explain to its clients what it is about to do, unwilling to frighten them. Farai, having already read the hostiles’ tone on the comm, tells Murderbot to do whatever is necessary to keep the attackers away from Sofi. Satisfied, Murderbot removes the wrap Naja had loaned it and opens the hatch.

Two young, expensively dressed attackers are surprised to find Murderbot waiting. It takes control of their pod’s systems via drone, then disarms and incapacitates them. It determines from their clothing and equipment that they attack travelers for entertainment rather than out of desperation, which makes it angry. It secures them to the pod’s safety rail, seals the hatch between the pod and the flyer, and tells the humans it will return shortly.

Murderbot rides the lifting field up into the hostile aircraft’s cargo bay, hacks its systems, and locates five more attackers in the main compartment. It walks in unannounced, and one attacker’s scream sets off a general panic. When another reaches for a stun weapon, Murderbot’s warning causes him to drop it. To provoke a charge, Murderbot tells them their two crewmates are dead, but the group collapses in tears. When the attackers claim they were only helping lost travelers, Murderbot plays back video from their own archive showing a previous assault on other victims. One attacker then points to a news alert: a story identifying a rogue SecUnit as stealing a tourist flyer and taking hostages, accompanied by a grainy image of Murderbot at the attraction platform.

Killing the attackers would reinforce that story and shift blame onto the other rogue unit. Instead, Murderbot sedates them, retrieves the two from the pod, and uses the pod to transfer its own group to the hostile aircraft. Once aboard, Farai and Naja administer sedation to all seven attackers. The unconscious attackers, along with an evidence packet of their crimes attached to their personal feeds, are loaded back onto the tourist flyer, which Murderbot sets on autopilot back along their route. The group departs in the larger, better-equipped aircraft.

Once underway, Farai apologizes and says she should have trusted Murderbot’s judgment. Murderbot admits that her earlier words had mattered because they told it she would not hate it for killing the attackers. Farai replies that she would have hated herself, but that Murderbot would simply have been doing its job. Murderbot privately flags the exchange as worth reconsidering its policy of avoiding honesty.

They land at a large interior port, where Murderbot alters the aircraft’s records to prevent the attackers from reclaiming it. The group uses bubble pod transports to reach the border of their target zone. A guard warns them that they are entering a high-conflict area due to a trade dispute between two supplier corporations, Allvahill and Izolineer. Murderbot cannot rule out B-E exploiting the conflict as cover. When Farai quietly asks whether they should still proceed, Murderbot nods, and the guard waves them through.
