The Last Frontier Episode 6 recap: Meet Dr. William Wigg, a chilling new menace

The episode of The Last Frontier opens with a massive blackout all over Fairbanks. Amid the darkness, we see an EMT unit arriving at what looks like an accident scene. When one of the EMT medics stepped out to help a man who looked like he was having a seizure, the injured man counterattacks, and the medic collapses as he creepily says,

"It'll all be over real soon."

Meanwhile, the man also harms the other EMT who went to grab a medical unit and injects her with something lethal. Turns out, it's none other than Dr. William Wigg. He arrives under the guise of a medic. But Sarah informs Frank about him since he obviously looks unfamiliar. Wiggs does not heal. He weaponizes medicine.

Soon, the hospital corridor becomes a stage for his calculated cruelty. How? He gets hold of Claire in the elevator and threatens her to call the flight medic and tells them about a patient who needs to be transported by air ambulance to Alaska Regional. We learn that the true identity of Dr. William Wigg is, as Hutch reveals,

"Our fugitive is a physician named Dr. William Wigg, aka the Angel of Death. This guy's smart, Yale-educated, board-certified in neuro-oncology, well published. He's also a serial killer. Court records say Wigg poisoned as many as 36 of his own patients and fellow staff members.

Hutch further continues,

In 2005, he was convicted of capital murder and spent the last decade in Pelican Bay. He exhausted all his appeals this month and was being transported to Terre Haute for execution when our JPATS went down."

Sarah's instincts pull her into the fray. She wants to fix things. That drive nearly costs her. Wigg's confidence makes him uncanny. He talks like a man convinced of a moral verdict only he can issue.

Wigg claims knowledge about a downed pilot, Timothy O'Bannon. He uses that knowledge as leverage. His demands are oddly specific and almost banal. He says that he has a safe deposit box at First Federal Bank in Seattle (Box No. 337) and he wants the bank's president to bring it to him by 6:00 am. He remains calm throughout, and that makes it more terrifying.

Frank gets more information about the accident site from where the medics found Wigg. Cole starts a search operation for the missing pilot with guns, flashlights, and search dogs. Sydney stumbles upon a dead bearded man who turns out to be the EMT. Meanwhile, in the dark room, the pilot whispers in pain.

The Last Frontier Episode 6 recap: Fairbanks blackout causes ultimate chaos

The town-wide power loss reshapes every sequence in this episode of The Last Frontier. Darkness breeds improvisation. Havlock and Frank fight on different fronts. Havlock's past in Kyiv, Ukraine, surfaces in a flashback. He even saves a life. That history complicates him. He is morally ambiguous but human. The past is a shield and a target.

Coming to the present, Frank scrambles to juggle three problems all at once, rescuing survivors, tracking down fugitives, and handling the political rot beneath in The Last Frontier.

Elsewhere, Sydney's choices catch up with her. Her old CIA ties and decision cast long shadows. The hard drive subplot widens here. Decryption brings a new threat, a proof of sabotage. The proof changes the stakes. Sydney moves from survivor to target.

Sydney asks Frank about whether he spoke to the OSI about retaining the hard drive. Sydney worries about it, and she explains that it's not Archive 6 but malware. She further reveals that the JPATS crash was a failed assassination attempt, and everyone on the plane was meant to die.

She reveals that two years ago, she was assigned to eliminate a high-profile Chinese diplomat and make it look like a plane crash. She further explains how Levi and she shared a plan with the Agency that they wanted to duplicate a plane crash. They wanted to feed malware into a plane, malfunction it and make it crash. Even though the agency liked their plan, they shelved it because they thought it was too risky. But now, if the drive was recovered, the blame would fall on Sydney. She begs Frank not to give the drive to the FBI. The show makes clear that institutional power is as lethal as any villain.

The team scrambles to find the pilot and arrange for the plane carrying the bank president to land safely. In the end, Frank tries to communicate with Havlock, and he assures Frank that the pilot is alive. Frank then orders a massive search operation.

Meanwhile, someone from the team records Frank's conversation with Havlock, and they find a crucial clue: church bells at 2:00 AM. The team locates him near an abandoned theatre. The officers reach the location and search the area. Before the officers, Courier was already present there, ready to harm Havelock. Havelock takes the stairs to escape, but Courier finds him.

However, Courier falls, and Havelock puts a gun to his mouth and asks him whether Sydney knew about the plan. Before he can answer, Frank arrives, Havelock escapes, and the Courier is arrested.

The Last Frontier Episode 6 recap: Is the pilot saved, and can they stop Dr. William Wiggs?

In Episode 6 of The Last Frontier, Fairbanks residents come forward and help with the makeshift emergency landing. They light up the runway with their vehicle's lights. The plane with the bank's president and the Wiggs' safety deposit box arrives, and Wiggs gives away the pilot's location. Soon, the team rescues the pilot, and he's alive. Wiggs opens the box, and the mementos (photos) reveal Wigg's monstrous pattern.

He kept the photos of the victims as trophies. He then picks a photo of a young man called Henry and tells the bank president that her son was his first victim. What happens next is not surprising at all. A grieving mother confronts him for killing his son and finally shoots Dr. Wiggs multiple times. Justice is served in this episode of The Last Frontier.
