Rat Trap is another great episode of MobLand that delivers escalating pressure, sharp performances, and a tightening noose of suspicion that keeps the series gripping even as it piles on complications.
By the time Episode 4 arrives, MobLand has established its world of interlocking criminal families, uneasy alliances, and the constant grind of damage control. Tom Hardy’s Harry Da Souza remains the battered centre of gravity, a fixer whose competence is both his greatest asset and the thing that keeps dragging him deeper into other people’s messes. This episode sharpens the focus on mistrust within the Harrigan circle while forcing Harry to carry on his work while the eye of suspicion turns towards him.. The result is an episode that feels denser and more psychologically loaded than some of its predecessors, balancing crime-drama mechanics with personal fallout.
The episode opens with Harry handling a messy loose end involving Bella and a shady associate, Antoine. Hardy plays these scenes with the weary precision that has defined his performance so far: polite menace, sudden physical dominance, and a refusal to be bought or delayed. The scene is efficient and unsettling, establishing early that Harry’s day job involves cleaning up after the family’s more impulsive members. From there the story branches outward. Conrad (Pierce Brosnan) learns that a body has been recovered, immediately raising the question of who knew its location. Only a tight circle had that information, and the resulting suspicion lands heavily on Harry. Maeve (Helen Mirren) fans the flames with characteristic cool calculation, while the family dynamic reveals itself as a web of old grievances, manipulated loyalties, and carefully withheld truths.
The episode cuts these power struggles with quieter, more intimate damage. Harry’s relationship with his wife Jan remains strained by the constant proximity of danger and the practical realities of their living situation. Conversations about home, safety, and the cost of Harry’s work highlight the strain it all put on family life. Elsewhere, the care home subplot causes a dark piece of Kevin’s history to resurfaces in a way that explains his character without turning him into a walking trauma explanation. Flashbacks and carefully loaded dialogue sketch a past that still shapes present behaviour, giving the episode emotional stakes beyond the immediate threat of gang warfare. These personal strands prevent the story from collapsing into a straight forward crime story.
The main part of the episode is the tension that revolves around whether Richie Stevenson has bought the carefully constructed narrative about his son’s death. Harry is summoned for a final test, and the scene that follows is among the most brutally effective in the series so far. The physicality is unflinching, the stakes personal, and Hardy’s performance conveys both professional detachment and the private cost of repeatedly proving his usefulness. The demand that follows requiring the Harrigans to attend his son’s funeral, raises the temperature further, turning a potential de-escalation into another opportunity for public performance and private calculation. In this world, peace is rarely clean and never permanent.
Helen Mirren continues to steal scenes as Maeve. Her scenes with Eddie clarify the extent of her influence and the long game she appears to be playing. Mirren’s delivery is deceptively maternal one moment and steely the next; she makes the character’s manipulations feel both inevitable and quietly horrifying. Brosnan’s Conrad is given more room to operate here, and the combination of patriarchal authority and growing paranoia suits him. Lara Pulver’s Bella remains a wild card whose independent deals and complicated history with the family introduce another layer of risk.
Rat Trap is preoccupied with loyalty tests, the difficulty of knowing who is truly on your side, and the way past violence continues to dictate present choices. The title is literal in places and metaphorical throughout. Suspicion spreads like a contaminant. Characters who should be natural allies eye one another warily. Harry’s position as the reliable outsider who has become indispensable grows more precarious with every successful intervention.
At times the accumulation of complications, new suspicions, old traumas, parallel schemes, and the introduction of additional figures from Harry’s past can feel slightly overstuffed. The series is still building out its world, and a lot of this still feel like set up for stuff to come. Some of the family revelations, while effectively staged, risk tipping into soap-opera territory if not carefully balanced in future episodes.
The episode strengths out weigh its weakness by far. Hardy remains the indispensable anchor, conveying a man who is simultaneously indispensable and increasingly isolated. Mirren and Brosnan give the Harrigan power structure genuine presence and menace.
Episode 4 succeeds because it understands that in this particular criminal ecosystem, the most dangerous moments are not always the loudest. A quiet conversation about the past, a carefully worded reassurance, a demand that masquerades as a request, these can be as lethal as any act of violence. Rat Trap tightens the screws with confidence, deepens several key characters, and leaves you with a clear sense that the next moves will carry heavier consequences. It is a strong, absorbing chapter that raises the temperature for whatever comes next.
