Phil and Suzie investigate when a toddler is found wandering the streets covered in blood – blood that doesn't belong to him. With both of his parents missing, it becomes a race against time to save them from one another – but when the boy's father is found slumped in a shallow grave in some woodland, Phil and Suzie try to uncover the truth behind two conflicting accounts of domestic violence. Meanwhile, Sam and Stuart investigate a stabbing in the local shopping centre. The victim is shaky when attempting to identify his attacker, but determined to get a result, Turner pressures him into positively identifying his prime suspect, Trey Harper – who soon turns out to be innocent.
