Quebec, 1956. The destinies of Nelly Maloye, a novice private eye, and Simon Picard, a research scientist at the local university, unexpectedly meet. Bankrolled by an ambitious client, the impulsive and headstrong Maloye joins the methodical and pragmatic Picard in a dubious quest to prove the existence of the elusive Yeti. For guidance, Simon carries with him an explorer's journal that supposedly contains the location of the mythical creature's den. Along with Tensing, their young Sherpa guide, and Jasmin, a chatty myna bird, the brave-hearted heroes come face-to-face with countless dangers during their trek through the heart of the Himalayas.
