Boulton is paired with new DC Kerry Holmes to investigate a gang who have been purchasing bikes with cheques stolen in an armed robbery. Boulton is keen to speak to Michael Duggan, a prime target that has evaded his capture for some time. Duggan, however, offers Boulton a deal - his brother-in-law, Sean Massey, is involved in a highly lucrative drug deal, and he knows the time, location and other parties involved. Boulton arranges a sting to catch the dealer red handed - however, Duggan does a runner with the money that Massey is due to hand over, and the dealer claims that Massey was told by his brother to plant the drugs on him. Holmes, however, has an idea on how to unravel the situation.
