London, 1878. When the body of a prominent judge's daughter is found on a boat in the Thames, the Scotland Yard director gives the case to Michael Corravan. An Irish former bare-knuckles boxer who is now a Senior Inspector, Corravan abandons his ongoing case, a search for the missing wife of shipping magnate Mr. Beckford, handing it over to his young colleague, Mr. Stiles. When more bodies are found on boats, Corravan and Stiles discover that the river murders and the case of Mrs. Beckford may be linked through some terrible act of injustice in the past.
