What Happens in Arrowhead: Full Plot Summary

The whole story of Arrowhead (2015) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

On a remote mining colony, Kye Cortland, Dan Mor, is pulled into a desperate escape from a political prison. He is forced to amputate his own foot to save himself and the other prisoners from being shredded by the relentless mining machinery. Cortland is recruited into a rebellion against General Lang, who emerged victorious in a civil war against General Hatch. Hatch, a driven strategist, explains that Cortland’s father—an important figure in the rebellion—is destined for execution in a few months on Lang’s anniversary. With his skills as a pilot, Cortland is asked to hijack a scientific vessel, retrieve its data, and use it to help Hatch break his father free. He accepts, receiving a cybernetic foot to bolster his abilities.

Onboard Arrowhead, Cortland wakes from suspended animation and begins to infiltrate the vessel’s data banks. He worries that hacking the system could lower the ship’s defenses, but Hatch—Mark Redpath—assures him that the risk is temporary and controlled. A violent EMI flare disrupts the ship and damages it, forcing the craft to eject all the escape pods. Cortland escapes in a shuttle and lands near the pods on a desolate desert moon. The ship’s AI, RE3F, voiced by Shaun Micallef, warns him about a toxic atmosphere but refuses to grant a usable login without proper credentials. Amid the turmoil, Cortland must navigate a dangerous world where trust is scarce and every decision could cost lives.

Exploring, Cortland discovers the body of Norman Oleander, [Christopher Kirby], the ship’s former security chief, and an intact pod containing biologist Tarren Hollis, [Aleisha Rose]. He brings Hollis back to the shuttle and, after reviving her, uses her biometric data to activate RE3F. Hollis divides her loyalty between suspicion and pragmatism, arguing that Hatch has resorted to terrorism; Cortland, however, resists the accusation as propaganda. Hollis, who recognizes Cortland as a soldier who once served with her father, offers a fair trial if he accompanies her to a rendezvous point where survivors might be rescued. Cortland declines but then reappears when RE3F refuses to start the engines using Hollis’ login. A hostile insectoid attack suddenly erupts, seemingly killing Cortland and foiling the rescue attempt. A nearby obelisk resurrects Cortland, infesting him with a symbiote that heals every wound, including the severed foot, and Hollis and Cortland drag Oleander’s body to the same obelisk, reviving him as well and unlocking RE3F’s full functionality with Oleander’s biometric data. Hollis urges Cortland not to abandon Oleander, but Oleander’s revival turns him violent, and Cortland must kill him, collapsing soon after.

When Cortland comes back online, RE3F reveals Cortland was dead for thirty-four days. The symbiote has revived him again, and Hollis has vanished, apparently killed. With RE3F’s help, Cortland works to restore the shuttle’s power and escape the moon in time to try to rescue his father. He learns that the symbiote compels a transformation into an insectoid creature during times of extreme stress or pain. After an out-of-control transformation, Cortland misses his father’s anniversary. He withdraws from the world, spending three years on the moon, bonding with RE3F and learning to regulate his new form. During this solitude, an insectoid creature continues to hunt him; using RE3F’s data, Cortland discovers the creature’s origin in Oleander’s cells. He sets a trap and, in a dramatic confrontation, kills Oleander by sacrificing himself, only to be revived once again.

RE3F cannot offer information on its own; Cortland must ask questions to unlock knowledge. A chance remark reveals that Hollis survived the fight and may have escaped the moon. Frustrated by RE3F’s secrecy, Cortland scavenges shuttle parts to upgrade RE3F, giving the AI a mobile frame. He organizes an expedition to uncover Hollis’ fate and, while exploring a deep cave, uncovers two original bodies—Oleander and Cortland’s own—merged into a strange organism embedded deep within the planet. Cortland finally destroys Oleander and attempts suicide, but fails, triggering a self-preservation response that revives him again. Hollis had left the moon aboard another pod.

In late revelations, RE3F illegally provides Cortland with confidential information, exposing that the moon is the target of a relativistic time-dilation experiment. Hatch and Lang intend to use the moon as a weapon in their ongoing conflict. Hatch lands on the moon and reveals that only minutes have passed for him, having captured Hollis and threatening to kill her unless Cortland yields the data. Realizing Hatch never intended for Cortland to survive, Cortland refuses. He wounds Hatch with a grenade hidden in his cybernetic foot, then kills him by undergoing a final transformation. Hollis talks him down and helps him revert to a human form. With Hatch defeated and the data secured, Cortland and Hollis plan to leave the moon, determined to free Cortland’s father and everyone else caught in the crossfire.

  • prison escape
  • self-amputation
  • mining colony

Q2

What is the symbiote that infects Cortland?

The symbiote is an alien organism from the obelisk on the desert moon. It resurrects Cortland after death, healing all his wounds including his severed foot. The symbiote also grants him the ability to transform into an insectoid creature during times of extreme stress or pain, though it also compels violent behavior in others infected by it.

  • symbiote
  • obelisk
  • transformation
  • alien organism
Q3

Why did Oleander become violent after revival?

When Oleander was revived using the obelisk's biometric data, the symbiote infection turned him hostile and aggressive. Despite Hollis urging Cortland not to abandon him, Oleander immediately attacked and shot Hollis, forcing Cortland to kill him in self-defense.

  • Oleander
  • revival
  • hostility
  • symbiote infection
Q4

Q5

Why did Hatch betray Cortland?

Hatch never intended for Cortland to survive the mission. When Hatch arrives on the moon, he reveals that only minutes have passed for him while Cortland has been stranded for years.

  • Hatch betrayal
  • Cortland sacrifice
  • data
  • Hollis capture
Q6

How did Cortland survive being dead for 34 days?

After killing Oleander, Cortland collapsed from his wounds and died. The symbiote from the obelisk resurrected him, revealing he had been dead for thirty-four days. The symbiote's healing properties revived him again each time he died, effectively making him immortal as long as the symbiote remained.

  • death
  • 34 days

Q7

What happened to Hollis after the insect attack?

  • Hollis survival
  • escape pod
  • moon escape
Q8

Why did Cortland miss his father's rescue attempt?

After his first transformation into an insectoid creature, Cortland lost control and went into a berserk state. This out-of-control transformation caused him to miss the critical anniversary date when he was supposed to rescue his father from execution. The guilt and failure led him to withdraw from the world for three years.

  • father rescue
  • anniversary
  • transformation
  • three years
Q9

What was the merged organism found in the cave?

During his expedition to find Hollis, Cortland discovered two original bodies, his own and Oleander's, merged into a strange organism embedded deep within the planet. This revealed the moon itself was connected to the time-dilation experiment and that both men's original bodies had been absorbed into the planetary organism.

  • merged bodies
  • cave
  • planet organism
  • time dilation
Q10

How did Cortland defeat Hatch on the moon?

When Hatch demanded the data and threatened to kill Hollis, Cortland wounded Hatch with a grenade hidden in his cybernetic foot. He then killed Hatch by undergoing a final transformation into his insectoid form. Hollis talked him down from his rage, helping him revert to human form before they escaped together.

  • Hatch defeat
  • grenade
  • transformation
  • cybernetic foot
Q11

Why did RE3F refuse to start the engines?

The ship's AI RE3F refused to start the shuttle's engines without proper biometric credentials. Hollis's login initially activated RE3F, but the AI later denied engine access using her credentials. Only by using Oleander's biometric data, obtained after reviving his body at the obelisk, was RE3F's full functionality unlocked.

  • RE3F
  • biometric
  • engine login
  • Oleander data
Q12

What caused the EMI flare that damaged the Arrowhead?

A violent electromagnetic interference (EMI) flare disrupted the Arrowhead vessel during Cortland's infiltration mission.
