Is it wedding bells for confirmed bachelor Skyler Foxe? The rocky road to marriage keeps the high school English teacher on edge, yet his football-coach-fiancé, Keith Fletcher, seems far too cool by half. Still, as the nuptials draw near, strange things seem to be plaguing Skyler. Small things that seem like little accidents and coincidences. Until he receives a mysterious package that leads him to the inescapable conclusion that someone may be trying to kill him. Keith and Skyler's gang of friends put their heads together to investigate. And then the wedding day comes off without a hitch, and Keith and Skyler go off on their surprise honeymoon for a weekend cruise. But Sidney and the SFC discover that Skyler is still in danger and secretly follow. Rather than ruin Skyler's one-and-only honeymoon, they hitch a ride. Can Sidney, Jamie, Rodolfo, Dave, and Philip keep out of sight of the happy couple and at the same time catch a killer before the cruise ends in murder? It's the Scooby Gang to the rescue! What could possibly go wrong?
