Philip Scott (Stephen Boyd) runs a secretive spy agency which manages to get results behind the Iron Curtain where the main Western agencies fail.
However, while on a mission he meets Toni (Camilla Sparv) and falls in love. Back in England, an Eastern Bloc group of spies led by Smith (Leo McKern) use this connection to put pressure on Scott to betray his spy network...
This is a fine enough late 60s spy film but tries to be in the Bond and LeCarre styles simultaneously. Unfortunately, it fails at both and becomes bogged down in the middle act where not a great deal happens. The 1960s feel, and the Cold War espionage setting, are still enjoyable. The twists are also very good.
