Dutch Kiki Bosch sits in her car, shivering, her skin blue. Eyes closed; she calmly explains to the documentary crew that despite appearances, she is fine. The cold blood at her extremities is mixing with the warm blood in her core, bringing its temperature down and leading to her current situation. Again, she assures everyone that she is fine. There’s potentially good reason to feel concerned though. Before being in the vehicle, Kiki Bosch has just spent an extraordinarily long-time swimming in some of the coldest water in the world, wearing nothing but a regular bathing costume. For some, the contemplation of taking a cold bath is torture. However, for Bosch, freediving into icy depths is not just a career, it’s part of a continuous journey into expanding her mindset.

Directed by underwater cameraman, Nays Baghai, Descent allows Bosch to sit down and tell her story. Starting off as a psychology student, she discovered the joys of freediving, and she was soon taking tour groups around Thailand. Sadly, she was raped by a colleague who would go on to do the same to someone else. This, unsurprisingly, led to a downward spiral for the freediver. Feeling guilty for not reporting her rapist and blaming herself for the assault, Bosch goes on to associate her freediving hobby with what she went through.

Descent captures Bosch casting off the oppression of being a victim and being reborn as an ice free diver. For Bosch, plunging into cold water helps her focus. Those familiar with the practice of mindfulness will recognise a strain of this in her swimming. Jolted by the cold, she remains acutely aware of where she is at that given moment, not the future and certainly not the past.

Bosch’s lo-fi narration accentuates the gorgeous scenes of clear blue seas and lakes. As the audience, we’re introduced to a whole new way of seeing the world. And just in case we’re too swept away in its majesty, Descent reminds us how dangerous it can be by telling us about Bosch nearly dying of hyperthermia while shooting a short film.

The key theme for Descent is ‘uplifting’, so we’re never allowed to ponder too long on what propels someone to test their body to this extent. Even when Bosch admits that doctors have told her she could lose her sight, Descent never asks us to question her methods.

Is that a bad thing? No, not necessarily. However, it does have the potential to paint an unrealistic picture of trauma/depression treatment. Just going for a run doesn’t automatically cure your anxiety, for example. For Bosch, freediving has allowed her to expand her mindset and reset her thinking. And then in the last minutes, we’re introduced to her new career as a Wim Hof method instructor, and the documentary essentially turns into a paid advert for the practice; the camera lingers on PowerPoints and graphics in her lectures, souring the au natural feeling of the overall documentary.

Is that a cynical note to take away from the whole thing? Perhaps. However, it doesn’t distract too much from Baghai’s direction and camerawork. Seriously, it needs to be seen at the highest definition. Bosch’s story, too, is one of reclamation and rebuilding. She was dealt a miserable hand, and she managed to rise above it. Given the current state of affairs, you can’t begrudge anybody for trying to find their place in the world and successfully doing so. More power to her and others like her.
