Cast for season 15, episode 73 "Security"

Stanton and Proctor investigate a vicious intimidation campaign against an officer from Barton Street, Steve Bennett, who is an old pal of Quinnan's. Mannion is hot on Brownlow's tail to get a result on the case, but Quinnan is sure that Bennett hasn't been entirely truthful. When Bennett eventually reveals that he has been having an affair, Stanton questions his mistress, but she provides a rock-solid alibi. When Mannion discovers a connection to a former intimidation case involving another officer from Barton Street, Stanton and Proctor enter HMP Long Marsh to speak to the villain responsible. Proctor then has a sneaking suspicion that a link to the officer's alarm system could prove the key to finding the culprit.

Trevor Byfield guest stars.
