Under a broad bridge on the ill-lit banks of Rome's silent Tiber River, a hapless prostitute lies dead. Six prime suspects and their distinctly different stories become inextricably intertwined, as an impoverished purse-snatcher; a suave former thief; two friends and penniless Casanovas; an impulsive young soldier, and a mysterious man in clogs tell their versions of what happened that fateful night near the quiet Paolino Park. Now, amid a heterogeneous group of potential killers, who all have something to hide, only one man is capable of committing such a hideous crime. Will he get away with murder?
