上世纪60年代末70年代初世界处于冷战之中。中苏珍宝岛冲突后，北京少年齐伟植随母亲疏散到秦岭腹地汉中市，经历了与那个年代政治氛围脱节、纯粹的少年性成熟期。 汉中，是冷战时期中国三线重镇。妈妈齐绣暄由于遭遇丈夫感情上背叛，她故意隐瞒丈夫的罹难，并对儿子相当冷漠。齐伟植缺失的母爱，在班主任周雯瑶身上得到回报，因而他对周雯瑶产生了微妙的情感

The world was in a cold war in the late 1960s and early 1970s. After the Sino-Soviet Treasure Island conflict, Beijing teenager Qi Weizhi evacuated with his mother to Hanzhong City in the hinterland of the Qinling Mountains, and experienced a pure juvenile sexual maturity out of touch with the political atmosphere of that era. Hanzhong was China's third-tier town during the Cold War. Mother Qi Xiuxuan deliberately concealed her husband's death because of her husband's emotional betrayal, and was quite indifferent to her son. Qi Weizhi's missing mother's love was rewarded by class teacher Zhou Wenyao, so he had a subtle affection for Zhou Wenyao.
