Nick O'Flaherty and Kelly Abbott join Ty and Zane at the wedding on an island in Scotland, thinking they're there to assuage Deuce's paranoia. But when bodies start dropping and boats start sinking, the four men get more involved with the festivities than they'd ever planned to.
With the clock ticking and the killer just as stuck on the isolated island as they are, Ty and Zane must navigate a veritable minefield of family, friends, and foes to stop the whole island from being destroyed.
