A mother dog and her three puppies live in a rusty mixing tank from an abandoned cement truck near the Gowanus Canal in Brooklyn, New York. A man in a stocking cap and a long coat lives close by, in a cardboard box under the Brooklyn-Queens Expressway. The man and the dogs live parallel -- but mostly non-intersecting -- lives, until the day one of the puppies becomes sick, and the man comes to her aid. This simple act sets in motion a chain reaction of goodwill: a veterinarian gives the man a job, a friend at a local diner helps find a place for him to live with the puppy he rescued, and men who work along the canal give homes to the other two puppies. In striking black-and-white etchings, Jonathan Frost captures the energy, forms, motions, and mood of an urban industrial canal while telling a tale of simple human kindness acted out in a stark cityscape.
