PLOT
When Yip Chi-Yan, Lau Chun-Hung, Sung Yee-Long, and Cheng Chun-Hin are brought together again by an accident, their lives change irreversibly. Chi-Yan is a radio host. She and the other three were members of the same band eighteen years ago. The memory of them playing music together comes back vividly to them, and so does the pain they have all tried so hard to bury. Eighteen years ago her boyfriend, Ka-Ming, was killed in a hiking accident. Time flies, but she can never forgive Chun-Hung, Yee-Long, and Chun-Hin for failing to save Ka-Ming. As they reconnect, the four good friends and the people around them are drawn into a vortex of love they have no control over.
