In "Trigger Point" Season 2 Episode 4, the tension reaches a boiling point as
Lana Washington and her team are pushed to their limits in the fight against the
terrorist group, The Wave. With each explosion, the stakes rise higher, and the
line between ally and enemy becomes increasingly blurred.

The episode begins with the aftermath of a devastating blast in central London, leaving Commander Francis to confirm the deaths of high-profile targets, including cabinet minister Matthew Palfrey. The shockwaves of this tragedy are felt throughout the team, but none more so than Lana, who is haunted by the loss of her colleague and friend, DCI Thom Youngblood.
As the team grapples with the implications of these events, Alex, the enigmatic informant from The Wave, emerges as a potential key to stopping the next attack. His warning of an imminent drone strike with multiple bombs sends the team racing against the clock once more. However, the trustworthiness of Alex is a constant question mark, as his loyalties seem to shift with each new revelation.
The expos' arrival at Bullion Wharf in East London is met with a series of explosions that defy expectations, as the bombs are discovered not to be drone-mounted but rather attached to scooters. The brutal nature of these attacks is a stark reminder of the ruthlessness of The Wave, and the horror is palpable as Lana witnesses a woman torn apart by one of the scooter bombs.
The emotional toll of these events takes its toll on Lana, who is confronted by her colleagues with concerns about her mental state. The specter of PTSD looms large, but Lana's determination to see the case through to the end is unwavering. Her refusal to step back from the investigation is a testament to her resilience, even as her personal life begins to unravel.
A visit to her parents reveals a family on the brink of collapse, with her mother's desire for a divorce and her father's despair over the death of Lana's brother, Billy. The tension between them mirrors the chaos of Lana's professional life, and her plea for them to stop blaming each other and start supporting one another is a poignant moment that underscores the theme of unity in the face of adversity.
Back at Counter Terrorism HQ, Lana's reckless pursuit of a suspect on a scooter earns her a stern rebuke from Hass, who accuses her of disregarding the rules and putting herself in danger. The accusation stings, but Lana's resolve remains unbroken, even as her commander's faith in her wavers.
The Wave's latest video, a call to arms against the wealthy elite, is a stark contrast to the opulence of Webster King's wedding, where the team races to defuse yet another bomb. The discovery of the IED in the staff toilets and the successful extraction of the device is a small victory, but the wedding's aftermath leaves a bitter taste, as King's concern for his lost Range Rover seems to trivialize the human cost of the day's events.
As the team investigates the connections between the attacks, they uncover a link between the targets that points to a common owner: Webster King. The revelation that King's businesses have profited from government bailouts while facing bribery investigations adds a layer of corruption to the narrative, and the team begins to question whether The Wave's targets are chosen at random or with a specific purpose in mind.
The episode takes a dramatic turn when Alex, now a fugitive from The Wave, reveals himself to Lana, begging for her help to stop the group's next attack. His backstory, involving the tragic death of his daughter and his subsequent descent into The Wave's ranks, is a heartbreaking tale that tugs at Lana's sympathies. His plea for her to trust him, despite the risks, is a gamble that could either save countless lives or lead to even greater tragedy.
As the episode draws to a close, the question of Alex's true loyalties hangs heavy in the air. Is he a genuine ally, seeking redemption for his past actions, or is he a master manipulator, playing Lana and the team for his own ends? The uncertainty surrounding his character adds a layer of suspense that keeps viewers on the edge of their seats.
"Trigger Point" Season 2 Episode 4 is a gripping installment that delves into the psychological warfare waged by The Wave, as well as the personal battles faced by Lana and her team. The episode is a rollercoaster of emotions, with each explosion bringing the characters closer to the brink. As the team navigates the treacherous waters of trust and betrayal, the race against time to prevent the next attack intensifies, leaving viewers eager for the resolution that the following episodes promise to deliver.
