Heaton mounts an operation to catch a relatively small-time drug dealer in an attempt to get the names of his suppliers - but the operation doesn't go completely to plan, leaving the hard evidence pointing towards the dealer's wife. However, Hardy isn't prepared to watch an innocent woman go to jail, and convinces the woman to spill the beans on her husband. Meanwhile, Fletcher and Casper investigate a case of criminal damage involving the owner of the local go-kart stadium, but discover his actions towards a disabled customer to be less than desired, and Perkins' misjudgment of the Max Little case leaves the man's mother in serious danger, after he turns up on her doorstep.
