迷幻少女遇著過氣公安老頭，紫葵未必是貓捉老鼠累鬥累，紫葵也可以是從老前輩身上學會認識自己。阿 P 為追阿初欠她的債，偶然與阿初的外公相遇，兩個生活態度南轅北轍的人，就是這樣在荒謬的處境中相互學習。阿P在當中看見年青一代的無奈：十六歲的迷途青春、愛情的無助、軟性毒品的蠶食、面對父母失敗的婚姻、自己渾噩的前途....阿初無故失蹤，又是否因抵受不了同樣殘酷的青春？世情像玻璃，有時看得透，有時不，相同的只是：兩者同樣冰冷易碎。The second feature from Hong Kong indie director Carol Lai is about the vulnerability of youth, made even more fragile by the vulnerable world of the adults. Grandpa Wu used to be a policeman in Mainland China and has now retired to a life of seclusion on an outlying island. One day, her daughter calls him up and reports that his granddaughter Ah Cho is again missing. The old man hits the road again, in search of the young girl. Then P, Ah Cho's best friend, emerges out of nowhere and heads Wu's search, leading the old man into a series of strange encounters in the uncharted world of frustrated youth.Source: 25th HKIFF (2001)
