Four childhood friends are reunited when one of them surfaces after twenty years, forcing them to confront a creature straight out of a spine-chilling Moroccan legend.

Five people with contrasting profiles compete for a position within Matsuika, a multinational corporation recently set up in Morocco. Following an interview with the C.E.O., they are advised to undertake a mysterious test in a secret location. It will determine who will hold the position. All five applicants accept and are led into a distressing bus with no windows. After endless driving, an accident occurs with the candidates trapped in the wreck. Thanks to a joint effort, they manage to evacuate the bus only to find themselves lost in the desert with their driver nowhere to be found. They start to wander, questioning the nature of the accident. Is it part of the test? Despite their will to survive and an urge to find clues, mirages of their most intimate fears begin to haunt them.
