城市的記憶、城市的慾望、城市的符號……一切的一切，跟你的記憶、你的慾望、你的符號……有什麼關連？本劇是台北人對台北的虛幻想像與真實體驗，是一個百年都市阿公的身世追尋，也是一個都市幼兒牙牙學語的自我認知。不論你是不是台北人，在此邀請你一同參與這趟奇異的旅遊，一起思考這個熟悉而又陌生，天天踩在我們腳下的城市－台北。
The memory of a city, the desire of a city, the symbol of a city......And what does everything have any connection with your memory, your desire, and your symbol? This drama describes the real experience and false fancy of Taipei people who feel about Taipei City. It is to trace to the history of an old man in the city of his lifetime. It is also to recognize himself for an infant who begins in babble. No matter you are or you are not a Taipei people, you are invited to take part in this adventure trip. Let's think about Taipei City, familiar and strange to us. Day in and day out, we tread upon the city, proceed to the next step, and recognize ourselves and the city once again.
