From This Day Forward

Come, share the joy...
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. They're being trained for their new job and will be touring the European continent, instead. Skiing in Gstaad, Switzerland, touring Venice, Italy, doesn't sound so bad, except that the two get sucked into a dangerous plot, with bad guys trying to kill them. Still, trying to figure out what the potential killers are planning might actually be easier than trying to figure out how to be married.
