The body of a teenage girl, Maria Cole, is discovered in a chalk pit, and the tracks of three different vehicles are discovered at the crime scene. They eventually lead D.C.I. Connor and D.C.S. Walker to the local hardman, Ray Harper. His son Andy and his friend Darren admit being at the pit on the same night, though they claim that they never saw the girl there. However, cracks soon appear in their story when CCTV footage reveals that they crossed paths with Maria before her death, later leading to the two boys being charged with her murder.
