Suspicions are rife and danger is mounting as ITV1 thriller Betrayal reaches a tense climax this week.

MI5 agent John Hughes (Shaun Evans) has been trying to foil a potential terror plot alongside colleague Mehreen Askari-Evans (Zahra Ahmadi), who has been seconded from MI6.

SUSPICIOUS

Last week, the pair survived a shoot-out with the security team of inscrutable Iranian general Qasem Asadi (Omid Djalili), who seems to have links to the possible threat.
