Quebec City, 1956. Nelly Maloye (LEFEVRE), a young apprentice detective, accidentally crosses paths with Simon Picard (FISHER), a research assistant in anthropology at the local university. Backed by a glory-seeking philanthropist, the intuitive but disorganized Nelly and the methodical, obsessive Simon set off on a wild adventure to prove the existence of the missing link in humanity – The Yeti! To achieve this goal, Simon relies on the coded diary of a lost explorer – a diary that should lead them to the mythic creature’s lair. Accompanied by Tenzig Gombu, a clever and enigmatic young Sherpa guide, and Jazzmin, a talkative mynah bird, our heroes confront a host of dangers in the heart of the Himalayas as they seek that legendary beast: the Yeti!
