Vince and his daughter Zoë travel to Terschelling for a father-daughter vacation. But he's come to the Dutch island with a sinister mission. Vince is carrying secrets and keeps it a secret from his 15-year-old daughter that he actually has other obligations on the island. Obligations that soon prove questionable and even very dangerous. Zoë then seeks out her own adventures with the local children, which she, in turn, keeps hidden from her father. The more father and daughter try to connect by keeping up appearances, the more they drift apart. When chaos and danger reach a peak, they need each other not only to save their bond but also, quite literally, each other's lives. Vince and Zoë turn out to be more alike than they thought. On vacation, you really get to know each other... above and below the water.
