Serve No Master.

On and beneath the meanest streets of Glasgow, fiery gangster Bart (Hoskins) is merciless with debtors, would-be rivals, and anyone else to whom he takes even a passing dislike. Danny (Li) has been kept as a near-prisoner by his Uncle Bart trained to attack, and if necessary, kill. Danny knows little of life, except the brutal existence that Bart has crudely and cruelly fashioned for him, but when Danny has a chance encounter with soft-spoken Sam (Freeman), he senses true kindness and compassion for the first time and experiences the transforming power of music. Danny sees a future for himself, however the mob will not give up on its prize pupil so easily, and Danny must soon fight again, to protect his new family and bury his troubles.
