But Caldwell is convinced that the KGB suspects him of treachery. He wants Gabriel to do the impossible and smuggle him over the Russian border to Finland. When Gabriel is ordered to help by his enigmatic handler Faith Green, he is pulled into a web of shifting loyalties and dangerous escape plans. As tensions rise and trust fractures, he is forced to confront the fine line between devotion and deception . . .
