DS Murphy finds himself going undercover with an INTERPOL officer to smash a car smuggling ring run by Godfrey Raines along with his son and daughter. Murphy manages to convince Raines that he too is a car thief specializing in high-end vehicles. He soon realizes that INTERPOL is after something else when they delay arresting Raines and start asking him about arms shipments. Into the picture comes a Mr. Davidson, former MI6 and now working the shady side of arms trafficking. Murphy isn't convinced that Raines is involved and looks for a connection between the two crooks.
