‘I truly required a break after that!’ The most nerve-wracking television episodes of all time

Spooks – I Spy Apocalypse from 2003

The episode begins with the intelligence unit locked down during a training exercise relating to a hypothetical terrorist attack, overseen by two Home Office officials. As events unfold, it seems an actual attack has occurred and a chemical agent deployed. The tension ratchets up as incoming communications show a crisis unfolding beyond their walls, and escalates as the boss appears to be infected, and the two Home Office officials attempt to leave, forcing Matthew Macfadyen’s character to choose between firing at them or allowing them to leave and potentially infecting the secure MI5 headquarters. This being Spooks, his decision is predictable.

The 1984 production Threads

Threads had minimal funding but arguably the most terrifying series I have viewed owing to its grim authenticity and dismal official figures. Viewed it recently having watched the original; I used to visit the pub in Sheffield featured in the show that highlighted the truth and the glib matter-of-fact official information which was broadcast. Continuing to be utterly horrifying 35 years later.

Severance – The We We Are (2022)

The season one finale of Severance has to be right up there among intense episodes. I was throughout the episode quite literally on the edge of my seat, pushing alongside Dylan to maintain his grip on the controls that sustained the Innies’ extended time, while shouting to the Innies to disclose their facts. The final climactic moment – “she is living!” – resembled a outburst.

Industry – White Mischief (2024)

Installment five in Industry’s third series had my heart racing. I was compelled to halt and rise and exit the space repeatedly due to the immense extent of the wanton self-destruction I saw. Rishi Ramdani is in deep shit at work and home – up to his eyeballs in debt from unscrupulous lenders due to his addictive betting, assuming hazardous chances on a wager involving sterling which may result in huge losses for his employer. Naturally, he embarks on a betting frenzy, consumes excessive substances and alcohol and experiences wins and losses, is brutally attacked. Each instance you believe things cannot decline more, it deteriorates. There is a chance for salvation by the episode’s conclusion but he squanders the opportunity, with horrifying consequences in the season finale. Certainly required a rest afterward!

Peep Show – Holiday (2007)

Peep Show is not inherently a tense series. But the episode Holiday contains such levels of cringe that it can cause you to stand the whole episode, filled with nervousness. The situation intensifies when Jeremy and Mark realize having to lie about the dog they unintentionally hit and later efforts to get rid of it. You subsequently use the rest of the installment wondering if it might be more awful than cremation, and it can be!

The 2001 The West Wing episode The Two Cathedrals

Nothing I’ve watched has been more intense 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 confidential aide and builds to a peak with a situation in Haiti, and the effects of the withheld information about the president’s MS condition, along with affirmation of his plan to run for another term. Excellent TV. Never bettered.

The 2018 Bodyguard premiere episode

The start of the British program Bodyguard, with the protagonist on a train accompanied by his small son, is for me one of the most intense episodes ever. He notices a Muslim female entering the restroom and knows something is off. The bomb squad is alerted, enter the train, and attempt to convince the woman to discard her bomb jacket. Tension escalates to a practically unendurable point, until yes, the vest is diffused.

Buffy the Vampire Slayer – The Body from 2001

Buffy comes into her home to realize her mom has deceased from natural reasons, which is the most unusual type of death in this supernatural show. The episode has no background music, a sullen tone, and we see the episode through the experience of Buffy’s astonishment upon finding her mother.

The Sopranos – Made in America from 2007

The ultimate sequence of the series finale of the program was incredibly anxious. And if you watched it when it originally aired, you – at the start – didn’t understand the cause. Tony’s enemies, real and imagined, were all overcome. This seems similar to the first season’s finale, right? “Think about the small elements.” However, the vibe is oddly threatening. Almost Twin Peaks levels of terror. The clan sits in an eatery. Meadow parks. Tony sorrowfully notifies Carmela problems are brewing with an additional associate working with the government. Meadow parks. Odd persons arrive at the eatery. Look at Tony(?) Meadow continues to park. Tony puts a record on the jukebox. Meadow finds a spot. The bell sounds, an individual enters. It isn’t Meadow, she remains parking. Tony raises his gaze. Continue. It stops. My heart sank roughly 20 minutes after.

The Walking Dead – The Last Day on Earth from 2016

I remained awake to view this installment at 2am. It was so intense after the buildup of bad guy Negan finding the group, mercilessly mocking his targets and then leaving the victim unknown (ended on a cliffhanger). The point-of-view shot from the victim and the subdued noises – ugh! {We then had to wait for season seven|We then needed to await season
