A group of musical anarchists stage sonic "attacks" in hospitals and banks, using found items as instruments and evading a tone-deaf cop with a burning hatred of harmony. Sanna is the leader of a group that stages impromptu musical performances in public places. Once they have taken their positions and turned on their metronome, there's no stopping the music. Meanwhile, anti-terrorism squad leader Amadeus Warnebring -- a frustrated cop who hails from a family of famed musicians -- vows to take down Sanna's sonic anarchists by whatever means necessary. ~ Jason Buchanan, Rovi
