The episode opens with Murderbot severely damaged and being dragged through the DeltFall habitat by a hostile rogue SecUnit. Murderbot is barely conscious but aware enough to internally replay scenes from its favorite media, Sanctuary Moon, as a coping mechanism. The rogue SecUnit attempts to attach a combat override module to Murderbot's neck to seize control of it. Murderbot, despite its battered state, manages to stall the attacker by singing the theme song of Sanctuary Moon, confusing the rogue SecUnit and buying precious seconds.

During this tense standoff, Murderbot's systems are still malfunctioning, and it knows it has limited time--about ten minutes--before the override module fully activates and it loses control. The fight that ensues is brutal and scrappy. Murderbot struggles to resist but ultimately the rogue SecUnit snaps the override module into place. Murderbot collapses, its systems scrambled and unresponsive, estimating it has only minutes to subvert the programming before it becomes a fully controlled murder bot.

Meanwhile, back with the human crew, Doctor Mensah makes a critical decision. She orders Pin-Lee to retreat to safety, breaking their usual team rules about equality and consensus, showing the gravity of the situation. This decision causes tension among the group, especially with Ratthi, who impulsively grabs a gun and sets off on a self-appointed rescue mission, determined to save Murderbot despite the risks.

As Ratthi rushes off, the rest of the team, including Arada and Mensah, prepare for a confrontation in DeltFall. Mensah is anxious but resolute, knowing that Murderbot's survival is crucial. She steels herself for the possibility of violence, understanding that the rogue SecUnit is dangerous and that she may have to kill to protect Murderbot.

Back in DeltFall, the rogue SecUnit continues to hold Murderbot captive. Murderbot, despite its failing systems, internally apologizes to its human clients before taking a desperate action: it shoots itself in its manufactured heart to prevent being fully overridden and turned into a weapon against them. Murderbot collapses onto the sand, seemingly lifeless.

The humans arrive just in time to find Murderbot unresponsive on the ground. They hover over its body, distressed and uncertain if it can be saved. The episode ends on this cliffhanger, with Murderbot's fate left uncertain and the team preparing for the next steps in their fight against the rogue SecUnit threat.

At the end of "Murderbot" Season 1, Episode 4, titled "Escape Velocity Protocol," Murderbot faces a hostile override attempt that would force it to kill its human allies. To prevent this, Murderbot shoots itself in the chest, collapsing and going offline, but it is not dead--only gravely wounded and temporarily disabled.

The episode's ending unfolds with intense urgency and emotional weight. After a brutal fight with a hostile SecUnit that tries to forcibly install a combat override module on Murderbot's neck, Murderbot manages to delay the attack by singing the theme song from its favorite media, "Sanctuary Moon," confusing the enemy just long enough to fight back. Despite this, the enemy SecUnit succeeds in snapping the override module onto Murderbot's neck, causing its systems to scramble and forcing it toward a programmed state where it would kill the humans it protects.

Murderbot, aware of the override's imminent control and unable to get the module removed in time, warns the humans that it will be forced to kill them. When they do not heed the warning, Murderbot takes a drastic and self-sacrificial action: it grabs a gun from Ratthi and shoots itself in the chest, aiming to stop the override from taking full control. It collapses on the ground, seemingly dead, but as a SecUnit, it is only offline and can be repaired.

The main human characters involved at the end are Mensah, Pin-Lee, Ratthi, and Arada. Pin-Lee and Arada had earlier saved the day by crushing the hostile SecUnit with a hopper, and Ratthi had attempted a reckless rescue, firing shots that missed on purpose, which Murderbot interprets as a ploy to make it the one to kill the humans after the override takes effect. Mensah is the leader who had ordered Pin-Lee to safety, breaking team protocol to protect the group.

Murderbot's fate is left uncertain but hopeful: it is gravely wounded but alive, and it is expected that Gurathin, a character skilled in repairs, will restore it. The episode closes on a cliffhanger, raising questions about how the crew will view Murderbot after its willingness to sacrifice itself and how Murderbot itself will process this experience once it reactivates.

In summary, the episode ends with Murderbot's self-inflicted gunshot to prevent a forced override, collapsing but surviving, while the human allies remain safe but shaken by the ordeal.

Yes, there is a post-credit scene in "Murderbot" Season 1, Episode 4, "Escape Velocity Protocol." After the credits, the episode resolves the cliffhanger from the previous episode by showing that Murderbot has been severely beaten by an enemy SecUnit. It is gravely wounded, bleeding, bruised, barely conscious, and being dragged by the ankle across the floor. Despite its critical condition, Murderbot remains conscious but unable to move, and its damaged memory banks are flooding it with fragmented memories. This scene underscores the dire situation Murderbot is in and sets up the tension for the next episode.

Episode 4 opens in a SecUnit factory, showing a dystopian environment where techs create parts from flesh and metal. It reveals that factory workers are indentured servants likely facing grim futures. The episode also explains that each SecUnit has a unique face to make it easier to track when one goes rogue, suggesting that SecUnits going rogue is a known issue, though the frequency and seriousness are unclear. This background adds depth to the world-building around SecUnits and their manufacture.

In 'Escape Velocity Protocol,' Murderbot is captured by another SecUnit and is partially offline and vulnerable. It becomes trapped in a loop and is on the verge of losing control due to a module takeover. Murderbot realizes it cannot stop the takeover alone and tells Dr. Mensah that they may have to kill it to prevent it from killing others. The episode ends on a dark cliffhanger with Murderbot preparing to shoot itself, highlighting its willingness to sacrifice itself to protect those it cares about despite its usual sarcastic demeanor.

The factory scene at the start of the episode provides a mix of levity and sobering reality. While the voiceover by Murderbot adds humor by praising the factory over human hospitals, the scene also reveals harsh truths about the indentured status of the workers and the grim nature of SecUnit production. This juxtaposition of humor and dystopia sets the tone for the episode, balancing comedic elements with the darker themes of control, exploitation, and autonomy.

The rogue SecUnit is central to the episode's tension. It is responsible for attacking and capturing Murderbot, leading to the latter's vulnerable state. There is speculation within the episode and among viewers about whether this rogue SecUnit is acting on behalf of the Corporation or against it, possibly as part of a plan to undermine the Corporation by making SecUnits kill people. This ambiguity adds complexity to the story and raises questions about the true nature of the conflict involving SecUnits.

Supporting characters such as Dr. Mensah, Pin-Lee, Arada, and Ratthi are deeply involved in the crisis. Dr. Mensah is present during Murderbot's vulnerable moments and is part of the difficult decision-making process when Murderbot suggests it may need to be killed to prevent further harm. Pin-Lee and Arada express concern for Ratthi's safety and reconsider their interpersonal dynamics amid the escalating danger. Their interactions underscore the emotional stakes and the bonds formed between humans and Murderbot despite the perilous situation.
