Internet songwriter Chow (Cherry Ngan) is gifted with an extraordinary retentive memory. She never forgets anything she has heard. One day, she was kidnapped by Yung (Ronald Cheng), a street punk, to a remote fish raft so desolate that an escape plan seems to be a mission impossible. In the hope to flee with the only ability she has, Chow offers to give a spiritual music therapy to the rather maniacal kidnapper.
A Yong is a reckless punk who liked everything with rhythm, fighting was one of them. His mood could only be soothed by a mysterious Demo music as his only spiritual sedative published on the Internet. When the gangster leader ordered him to watch over a girl kidnapped and imprisoned in a fishing boat of a fish farm. The girl tried to escape many times but was always stopped by A Yong. After they fought each other several times, A Yong was surprised to find out that she was the composer of that Demo. In order to escape, she pretended to be friendly and applied music as therapy for A Yong, but at the same time, both unknowingly changed in an awkward situation.—BL
