It's a trip that agent Paul Chevasse will never forget. His destination: the isolated republic of Albania on the Adriatic coast, at a time when the regime is at it's most repressive and the people live in daily fear of the secret police.

His job: to find a double agent whose cover has been blown and out him out of commission, permanently. But what Chevasse doesn't know is that deep within the twisting channels of the perilous coastal marshes, someone has set a trap for him - someone who holds the keys to hell.
