‘I truly required a break after that!’ The most nerve-wracking television episodes you’ve seen

The 2003 Spooks episode I Spy Apocalypse

The episode begins with the intelligence unit restricted during a training exercise about a potential terror incident, supervised by two Home Office agents. As the situation develops, it seems an actual attack has occurred and a chemical agent deployed. The tension ratchets up as reports reveal a catastrophe taking place outside, and intensifies when the leader seems contaminated, and the two Home Office officials attempt to leave, forcing Matthew Macfadyen’s character to decide between shooting them or allowing them to leave and potentially infecting the secure MI5 headquarters. This being Spooks, his decision is predictable.

The 1984 production Threads

The production was inexpensive but one of the most frightening programmes I have viewed owing to its grim authenticity and dismal official figures. Saw it not long ago following the initial broadcast; I often attended the bar in Sheffield from the programme that highlighted the truth and the offhand factual official statements which was broadcast. Still absolutely terrifying 35 years later.

The 2022 Severance episode The We We Are

The season one finale of Severance ranks highly in terms of gripping installments. I spent the entire episode quite literally on the edge of my seat, pushing alongside Dylan to maintain his grip on the controls that kept the Innies on overtime, while shouting to the Innies to reveal their realities. The final climactic moment – “she’s alive!” – was like an eruption.

Industry – White Mischief (2024)

Installment five in Industry’s third series made my pulse quicken. I was compelled to halt and rise and exit the space repeatedly because of the sheer scale of the reckless self-harm I saw. Rishi Ramdani is in major difficulty professionally and personally – up to his eyeballs in debt from unscrupulous lenders due to his addictive betting, assuming hazardous chances on a wager involving sterling that might cost his firm millions. Naturally, he embarks on a betting frenzy, does tons of drugs and drink and wins, loses, wins, gets beaten to a pulp. Every time you think it can’t get any worse, it does. There’s hope of redemption by the episode’s conclusion yet he wastes the chance, leading to terrible outcomes in the concluding part of the season. Absolutely had to relax following that!

The 2007 Peep Show episode Holiday

Peep Show itself isn’t necessarily a stressful show. Yet the installment Holiday features such degrees of awkwardness that it will make you rise for the full show, filled with nervousness. It all ramps up when Jeremy and Mark realize being compelled to falsify about the canine they accidentally run over and subsequent attempts to dispose of it. You then occupy the remainder of the episode wondering if it might be more awful than cremation, and it can be!

The West Wing – The Two Cathedrals from 2001

Nothing I have seen has been as tense than the first time I watched the concluding episode of The West Wing’s second season. The installment begins with the consequences of the demise (in a car crash) of the president’s private assistant and escalates to a高潮 with a crisis in Haiti, and the effects of the withheld information regarding the president’s multiple sclerosis diagnosis, coupled with verification of his aim to run for another term. Excellent TV. Unequaled.

Bodyguard – episode one (2018)

The start of the British program Bodyguard, with the hero aboard a train alongside his juvenile boy, is for me one of the most intense episodes ever. He spots a Muslim woman going into the loo and realizes something is amiss. The explosive disposal specialists are summoned, enter the train, and attempt to convince the woman to discard her bomb jacket. Tension escalates to an almost unbearable degree, until, indeed, the vest is disarmed.

Buffy the Vampire Slayer – The Body (2001)

Buffy comes into her home to realize her mom has deceased due to natural factors, which is the rarest form of demise in this paranormal series. The episode has no background music, a gloomy atmosphere, and we see the episode through the experience of Buffy’s dismay upon uncovering her mother.

The Sopranos – Made in America (2007)

The concluding moment of the last installment of the series was extremely nerve-wracking. And if you watched it when it originally aired, you – at the start – didn’t understand the cause. Tony’s adversaries, actual and perceived, were all vanquished. Surely this has the feel of the season one ending? “Think about the small elements.” However, the vibe is oddly threatening. Almost Twin Peaks levels of terror. The family gathers in a diner. Meadow finds a parking spot. Tony sorrowfully notifies Carmela problems are brewing with yet another of his crew working with the government. Meadow secures a parking space. Strange people enter the restaurant. Gaze at Tony(?) Meadow continues to park. Tony puts a record on the jukebox. Meadow parks. The bell sounds, an individual enters. Can’t be Meadow, she’s still parking. Tony glances upward. Continue. It stops. My heart sank roughly 20 minutes after.

The Walking Dead – The Last Day on Earth from 2016

I stayed up to watch this episode during the night. It was so intense after the establishment of antagonist Negan locating the survivors, savagely teasing his prey and then keeping the death a mystery (ended on a cliffhanger). The first-person perspective of the victim and the muffled sounds – ugh! {We then had to wait for season seven|We then needed to await season
