New York City's infamous jail Rikers Island houses nearly 7,000 detainees. Chefs, not inmates, do the cooking. And while they're on their shift, the chefs are locked inside, too. There are cameras everywhere, monitored from the guard's office. Dull knives are chained to heavy machinery. Can lids slide into a locked cage. Spoons are locked up in the office. Inside Rikers' kitchens, there's a delicate balance between the chefs, the guards, and the inmates who wash the dishes.
