In Canada on May 22, 2008, something unexpected washed up the sea on an island near British Columbia - a severed right foot with a sneaker. It was the fourth severed foot in the area in two months. Using the story of unexplained cases, we will explore the depths of science and human genius hidden behind forensic investigations. One of the cases where an unknown body was found in the fields will take us through a specialized world of forensic anthropology, where insects, pieces of paint, ballistics and DNA bring the individual pieces of the puzzle needed to solve the mystery.
