在这部无边无际片中,《非理性之美》讲述了一个不同寻常的男人，不顾一切追随内心梦想的故事。莱恩•桑德斯是一名南非超级马拉松跑者，他来到纳米比亚的鱼河峡谷，决心以最快速度穿越84公里长的峡谷山涧。没有任何理由解释他为什么要这么做，但是在狂野荒美的山谷里，他不藉借任何帮助，最终不间断、独自跑完了全程，用时6小时57分。
Human beings don't always make rational decisions. But making irrational decisions is precisely what makes us human. These decisions, based on an impulse or a feeling, often lead us to those perfect moments when it feels great to be alive 'The Beauty of the Irrational' follows Ryan Sandes, a South African Ultra-Runner, as he returns to the Fish River Canyon to run the 5 day, 84km, Fish River Canyon Hiking Trail in the fastest time possible. He completes the run, self-supported, in a record time of 6h57min.
