A no-frills British film about police officers who get boozed and bloodied while investigating football (soccer) hooliganism from the inside - they join the Shadwell Army, a group of footy fans with a sideline in GBH.
Films about cops with good intentions getting seduced by the seedier side of life while undercover aren't in short supply, but I.D. manages to hold its own even when placed next to them. It's believable and fully aware of its limitations, yet still manages to deliver a few surprises from time to time.
John (Reece Dinsdale) is the lynchpin of the story, but kudos to Warren Clarke, too, as bar-owner Bob, whose dialogue was like thuggish poetry.
