Concerto of the Bully (2018)

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.
