Peter Grimes lives from fishing. Raw and recluse, he finds himself at odds with the local community who accuse him of brutality towards his young apprentices and blames him for the death of one of them. A few friends stand up for him - Ellen Orford, a widow whom he wants to marry, Balstrode a retired sea captain, and an apothecary Ned Keene - but Grimes remains a mysterious figure. What really happened to his missing apprentice, and was he involved?
