The night manager of a Cairo hotel is recruited to infiltrate an arms dealer's inner circle.

An Englishman, Jonathan Pine, is working as the night manager of a Cairo hotel. He gets involved with a local woman who is the girlfriend of a local gangster. Through her relationship with the gangster she has acquired information linking illegal international arms sales with Richard Roper, an English billionaire. She is soon found dead, murdered due to her having this information. Fearing for his own life, Pine flees, ending up working at a remote hotel in Switzerland. Four years pass, and then Roper visits the Swiss hotel. This rekindles Pines thirst for revenge, and he is enlisted by British Intelligence to spy on Roper. What follows is a very dangerous game of intrigue and deception.—grantss
