Cryer, Smithy and McCann attend the scene of an RTA, where they find a supply of cocaine as well as two firearms in the boot of one of the cars involved. Smithy accompanies one of the victims involved to hospital, where he discovers him to be a member of the regiment in which Smithy served during his time in the army. Smithy enlists one of his old army buddies, Tony Mitchell, to do a little digging on his behalf on the quiet. However, when a CID operation is blown out of the water, McCann reveals Smithy's intentions to Meadows. Realising that his old friend is heavily involved with the operation himself, Smithy is torn between his loyalties to an old friend and his loyalty to the job.
