One ship. One missing person. Four thousand suspects.

Connor and Samantha Wolfe are finally taking their family on a much-deserved getaway aboard a luxurious cruise ship. Unfortunately, crime doesn’t take a vacation.

When a wounded man stumbles into a public bathroom, Samantha and her three-year-old son Andy rush out to find help. But when Sam returns, the man is gone–without a trace.

Now the race is on to find the missing man–and the one who shot him–before anyone else becomes a victim. Can Connor and Sam protect their family and the rest of the passengers? Or will their dream vacation become a nightmare?
