Shiang-Chyi just returned to Taipei from overseas. She meets Hsiao-Kang by chance. She once bought a watch from him when he was a street peddler. But now, Hsiao-Kang works as a porn actor. She isn′t aware about that. The Wayward Cloud starts off in a similar fashion as Ming Liang Tsai′s previous film The Hole but depicts human beings confined in obsession and solitude with a much stronger level of eroticism and pessimism. In order to survive in Taipei, which is notorious for its lack of water, Shiang Chyi fills up her water bottle secretly at the public restroom while Hsiao-Kang steals water from the water tanks up on the roof of the apartment. The Wayward Cloud depicts the disease of city people who have reached a hopeless state of solitude by alternating the obscene situation with the situation where the main characters are extremely thirsty. The first scene of the obscene sex act utilizing a watermelon is a scene in the porn film. After showing Shiang-Chyi staggering to find her key, a Japanese pom actress is shown to be in distress because of something that went inside her body while she was masturbating during a sex act. This devastating film which portrays the lives of people who lost the key that is much needed in each of their own lives, heightens the level of irony with an extravagant musical sequence. It′s a film that makes one ache in the heart with the despair and solitude that digs deep inside endlessly. (Kim Yong-jin)
