Shenyang, in deep winter snow. Two promising 12-year-old Beijing opera students, Dong ('winter' in Chinese) and Nuannuan (literally meaning 'warmth') are practising their stage moves diligently and fervently in order to secure their place in an upcoming performance in the capital. Nuannuan has a crush on Dong but Dong is lost in a daze - of a muted longing for his dead mother and a nameless affection for the girl's young aunt - which unfolds in the juxtaposing scenes of a lone balloon drifting away and a colourful kite soaring into the sky. The train is soon to leave for Beijing, a fond farewell has been bided. Dong has to make his journey, with or without Nuannuan.
