"It’s The Big Day. Sid Hackbirn and Lisa Wycherly are getting married. But in the days and weeks before the wedding, the pair discover that there is something very strange going on with their work as ultra-top-secret counter-espionage agents. Courier drops are coming in without the usual processing. The bad guys tailing them are unusually persistent. Then Sid and Lisa take off for their honeymoon only to find that the nice, relaxing vacation in England that they had planned will be anything but."
