Gritty and realistic, McCallum stars John Hannah (The Mummy, Four Weddings and a Funeral) as Dr. Iain McCallum, a motorcycling forensic pathologist with a passion for truth and more women problems than he can handle. McCallum investigates killings in London's East End with his dedicated team in the morgue at St Patrick's, including the beguiling Dr. Angela Moloney (Zara Turner, Sliding Doors).
