Amid the frozen emptiness of Alaska, The Last Frontier keeps unveiling new layers of suspense and trauma. In Episodes 3 (“Country as F**k”) and 4 (“American Dream”), the focus shifts between intense action and increasingly personal mysteries — especially those surrounding Frank (Jason Clarke), Sidney (Haley Bennett), and the elusive Havlock (Dominic Cooper).

Episode 3 — “Country as Fk”**

The third chapter delivers the show’s most spectacular set piece so far: a chase aboard a tundra buggy, a massive, train-like vehicle used by wealthy tourists to explore the Arctic landscape. Inside, chaos reigns — hostages, helicopters, and escaped convicts collide in a sequence that blends action absurdity with the nostalgic mood of an old-fashioned thriller.

Yet the episode reaches deeper than the adrenaline rush. Frank is still haunted by the loss of his daughter — who died just weeks before her ninth birthday — carrying physical and emotional scars that make him vulnerable. This pain connects him to Caleb, the young boy who escapes the criminals and finds refuge with him. Their bond adds humanity to a story that keeps growing darker.

Meanwhile, Sarah is found alive, but Havlock has left behind traces of his real plan — including a mysterious file printed during her captivity. At the same time, the show finally reveals what Sidney has been hiding: she not only knew Havlock intimately but also calls herself his “first victim.” Flashbacks show their relationship was far more than professional — and by the end of the episode, she drops the bombshell confession that she’s Havlock’s wife.

Elsewhere, Luke and Kira are still being held hostage by one of the surviving inmates. The danger is escalating, but Frank has no idea what’s coming — or what the spy on the run still intends to do.

Episode 4 — “American Dream”

The fourth episode takes a detour that feels self-contained yet reinforces the show’s procedural tone. Two fugitives — Kitty Van Horn and Vivian Pike — murder a State Trooper and go on the run, leaving behind one crucial clue: Havlock’s sweater.
Kitty, a black widow who killed three husbands and stole millions, and Vivian, a seemingly harmless con artist, make for a fascinating duo filled with twisted tension and warped sisterhood. The manhunt led by Frank is the episode’s highlight, balancing action and introspection. He remains ethical and compassionate even when it would be easier to shoot first. Still, fate turns cruel — Kitty tries to stab him from behind and is shot dead by Sidney.

While Frank maintains his moral compass amid chaos, Sidney grows ever more ambiguous. She admits that her marriage to Havlock began as a cover mission and later became something real. Yet her words sound rehearsed — and every sentence feels like a foreshadowing of a future betrayal.

Meanwhile, Havlock is very much alive, operating from the shadows. We learn he made suspicious bank transfers to a Russian hacker in St. Petersburg, linked to the theft of a classified CIA file, Archive 6. Now Sidney must intercept a courier carrying a copy of the archive all the way to Alaska before Havlock gets his hands on it.

On the other side, Sarah tries to return to normal life but hides a secret: she still keeps the memory card Havlock gave her. Fear of “another Chicago” — a still-mysterious trauma in the couple’s past — prevents her from telling Frank. When she decides to look for Luke and Kira herself, it’s too late: they’re still at the mercy of a delusional inmate, and their attempted escape ends in disaster.

Between Ice and Guilt

With these two episodes, The Last Frontier cements itself as a cold, human thriller. The frozen landscape mirrors the characters’ emotional wounds, and the suspense grows as the past returns to haunt them all. Havlock may be the ghost driving the plot, but the real hook lies in the emotional mysteries: what is Frank hiding in the basement? What happened to his daughter? And how far will Sidney go in her web of lies?
