一天，约翰尼·海沃德（池内博之饰）在一次公众集会中去世。警视厅凭着强烈的正义感，寻找刑警东居洪一良（竹野内丰饰）和当地警察渡边十字（大杉廉饰）进行调查，发现根本找不到嫌疑人。从垂下的蛛丝中，我们可以找到蜘蛛的位置。从马蹄的痕迹中，我们可以找到马的位置。事情留下的蛛丝马迹和蛛丝马迹都可以找到。唯一的线索就是死者临死前喃喃自语的奇怪话语。与此同时，知名散文家京子（松坂庆子饰）正在为神奈川知事选举做准备。她的丈夫、前神奈川县知事洋平（鹿内贵志）因病离任，京子高调参选自然引起了不少关注。在此期间，冬菊被上层勒令停止参与案件调查，他不得不想各种办法，在小时候认识的记者桐子（夏川结衣）的帮助下，秘密展开独立调查。却发现强尼似乎与京子有某种难以捉摸的关系，真相逐渐浮出水面。这部电影是根据森村诚一的同名小说改编的，该小说于1977年被改编成电影。

Ma Ma do you remember,
the old straw hat you gave to me,
I lost that hat long ago
flew to the foggy canyon.
Yeah Ma ma I wonder
what happened to that old straw hat
falling down the mountain side
out of my reach like your heart.
Suddenly that wind came up
stealing my hat from me yeh.
Swirling whirling gust of wind,
blowing it higher away.
Ma ma that old straw hat was the only one I really loved,
but we lost it.
No one could bring it back,
like the life you gave me.
Suddenly that wind came up,
stealing my hat from me yeh.
Swirling whirling gust of wind,
blowing it higher away.
Ma ma that old straw hat was the only one I really loved,
but we lost it.
No one could bring it back,
like the life you gave me,
like the life you gave me.
