Meadows is determined to bring one of his nemeses, Andy Burton, to justice for a safety deposit box robbery he committed in the 80's, for which there was little evidence to prove his involvement. In order to gather evidence on Burton, who is serving twenty years in Shadwell for armed robbery, he sends Glaze undercover into the prison. Glaze soon befriends a nonce, Ricky Sefton, who provides him with information on Burton's dealings, and when the pair become acquainted, Glaze finds himself in the middle of a delicate situation - breaking out of prison whilst holding a guard at gunpoint. However, unbeknown to him, Burton has already discovered he's a cop, and has already plotted his downfall. (thetvdb.com)
