The feature debut of Irish filmmaker Johnny O'Reilly, this Russian/Irish/British/German co-production is a novel variation on the classic "locked room" mystery. Told in flashback with disorienting cuts back and forth between past and present as the two stories move towards parallel time (all the more confusing because two characters in the different timelines are nicknamed Slava and characters addressing them sometimes triggers the transitions), seasoned investigator Andrey (Aleksey Guskov) and junior partner Slava (Anton Shagin, HIPSTERS) arrive at a remote mountain weather station when it loses contact with the base. Finding no bodies, no evidence of a struggle, and only a handful of enigmatic clues including bullet holes in a door (but no blood), a washing machine in the middle of the dining room, cans of sweet milk in various crawlspaces, and a recurring chalk drawing of a tree, the duo take to their figurative armchairs like Holmes and Watson and try to deduce from the clues what became of matchstick sculptor Ivanov (Vladimir Gusev), Yeti fantasist Drozdov (Sergey Garmash, NEWSMAKERS), and nineteen-year-old "invisible" cook Romash (Pyotr Logachev), so adept at hiding since he witnessed the murders of his parents and eluded the killer at five years of age. The unexpected visit from wealthy married spelunkers Vadim (Sergey Yushkevich) and Irina (Marina Aleksandrova) creates further tension among the psychologically-incompatible trio as Drozdov tries to sell Vadim on funding a yeti expedition and Romash is drawn to Irina. When Irina comes back injured from a disastrous cave expedition, Drozdov suspects foul play and is willing to profit from it; but the night brings a stalking presence that will reduce their numbers considerably by the morning. Is Romash the "boy who cried yeti" or is there really someone else out there in the snow driven to kill by something other than money and opportunism.
