Black Mirror ‘Metalhead’: Story and Ending Explained
Right from the off, the world of Metalhead is depicted as a rather desperate and hopeless one for our three protagonists. The early exchanges of banter between them suggest a close bond, as does the nature of their mission, which the dialogue suggests is one of a mutual concern to ease the suffering of a loved one. Their mission is to raid a warehouse for a special item, which we understand is an extremely dangerous undertaking.
Yet, only when the mission goes wrong do we comprehend exactly why that is. Hiding beneath the package Bella (Maxine Peake) and Anthony (Clint Dyer) are looking for is a “Dog.” Keen observers would have noted that “Dogs” were actually referenced in the very early dialogue exchanges between the protagonists in relation to the lack of wildlife (pigs), and it’s immediately obvious why there’s no longer an abundance of farm animals here. “Dog” is the moniker given to the machines that have hunted and killed the human population in Metalhead, and they’re absolutely terrifying.
After awakening, the Dog launches an explosive ball containing scores of sinister, sharp-looking tracking shards, which pierce Anthony’s face and strike Bella in the leg. It then quickly dispatches Anthony before turning its attention to the other fleeing protagonists. A car chase ensues, and after the Dog catches Clarke’s (Jake Davies) van, kills him, and then resumes chasing Bella (this time from the van), Bella is forced off the road and almost off a cliff. The Dog uses the tracking shard stuck in Bella’s leg to quickly locate her position, and though she’s able to cunningly trap the Dog within the vehicle and jump out before it rolls down the cliff, the Dog isn’t defeated. Importantly, though, one of its arms is ripped off after being caught in the twisted metal of the wrecked car.
Meanwhile, Bella puts some distance between her and the Dog, using the time to forcibly remove the tracking shard by painfully cutting it out of her leg. By placing it in a plastic bottle and floating it downstream, she hopes to deceive the Dog and its ability to track her. Unfortunately, her radio call home to explain the disastrous outcome of the mission and her attempt to return is immediately picked up by the Dog. Notably, during the radio call, Bella is unable to determine whether her allies can actually hear her and simply asks them to make a sound to acknowledge her. We hear a whistling noise that she assumes to be a response. But was it her friends back home or the Dog tricking her? It isn’t clear.
Pursued once again, Bella climbs a tree to evade detection but is quickly located. Luckily for her, the Dog isn’t able to climb the tree with its damaged arm. It powers itself down and opts to wait it out, but Bella seems to know this is likely also a tactic to conserve its energy. To waste its batteries, she throws candy at the robot, fighting her own exhaustion to constantly wake it up and force it to burn power. Eventually, it’s so depleted that it enters sleep mode. Having determined it is safe to move, Bella climbs down and makes a run for it.
Bella’s path leads her to an abandoned house with a car outside that looks to be in serviceable condition. She’s able to use a metal pole (an antenna?) to reach through the catflap in the door and grasp the keys inside the house. Though they aren’t the car keys that she’s after, Bella is able to take refuge inside, where she discovers the tragic and gruesome suicide of its owner. Battling the trauma of witnessing (and smelling) the gory demise of the house owner – who is laid on a blood-soaked bed, gun in hand – Bella grabs his gun and pries the car keys from his coat.
Unfortunately for Bella, though, only a little while after her escape from the Dog, it has recouped enough power to switch back on and resume its chase. Using the trail of blood dripping from Bella’s wound, it tracks her location to the house and easily overcomes the locked gate and door by jacking into its computer. As Bella begins to make her way out, she realizes she is not alone and hides in a room that is being refurbished. After being sprung, she uses a can of paint to cover the Dog’s onboard camera. The Dog – now clutching a knife in place of its broken arm – attacks the walls blindly as Bella flees the building toward the vehicle outside. But the car won’t start. Using the car’s stereo to attract its attention, Bella baits the Dog to attack the car. She then shoots the Dog twice with the shotgun, destroying it in the process.
However, the Dog isn’t quite done yet. In one final attack, it launches another explosive bomb full of tracker shards, which, just as they did to Anthony earlier, score hits directly to her face and neck.
In the final scene, Bella is seen in the house considering whether to try and remove the shards. But there are far too many lodged in her, one of which is in her throat and likely too difficult to remove. Furthermore, as Bella radios to tell her friends that she won’t be coming home and to pass on one final message of love to her family, we’re suddenly made aware of another terrifying truth: dozens of Dogs are on route to her position. Bella likely knows this and realizes that an attempted return would jeopardize the safety of her friends back at camp (wherever that is). She chooses to sacrifice herself, using her knife to end her own life and keep their location a secret.
As the camera pans away from her suicide, we’re shown a brief glimpse of the robots investigating Anthony’s corpse back at the warehouse. And as we do, we see the contents of the box the group was trying to locate is spilled onto the floor. It contains teddy bear soft toys.
