Czech director Bohdan Slama's gently rendered, bittersweet drama tells the story of a science educator troubled with uncertainty about his sexual orientation. Petr spends his days teaching students to understand nature, so we can understand ourselves,” yet self-knowledge is precisely his problem. Slama's poignant approach hinges on a double bind involving Marie's affection for Petr and his unrequited, awkward longing for her hunky son Lada. The sense of yearning is palpable not only in these characters' wonderful rapport, but in lenser Divis Marek's gorgeous widescreen vistas.
