In the opening episode of the fifth season of 'Erikoisjoukot,' contestants are immediately thrust into an intimidating challenge that involves swimming two kilometers in open water to reach a waiting boat. One of the contestants, social media influencer and YouTuber Pinja 'Pinkku Pinsku' Sanaksenaho, shares her deep-rooted fear of water, specifically the thought of not being able to see the bottom. She explains that her anxieties lead her to imagine being dragged underwater by an unseen creature, a fear that is both irrational yet vivid for her.

During the swimming challenge, the situation escalates when instructor Robin Hendry unexpectedly submerges the slowest contestants by pulling them down by their legs. Sanaksenaho, who had been vocal about her fears, falls into a state of panic at this unforeseen development. This incident highlights the intensity and psychological challenges faced by participants in this grueling competition, testing both their physical endurance and mental toughness under extreme stress.

As the season progresses, viewers can expect to see how the contestants cope with their fears and the various trials they encounter. The show not only emphasizes physical challenges but also illustrates the emotional and psychological journeys of the participants, making it a compelling watch for audiences seeking a mix of thrill and human drama.
