A mother and her three children struggle to survive on the most shocking sailing trip of their lives.

Since the death of her husband, Anne Dunne and her three children have struggled in every way. In a last-ditch effort to save her family, Anne plans an elaborate sailing vacation to bring everyone together once again. But only an hour out of port, their summer getaway is already turning into the trip from hell.

Anne’s teenage daughter, Carrie, is planning to drown herself. Her teenage son, Mark, is high on pot, and ten-year-old Ernie is nearly catatonic. Somehow, Anne manages to pull things together, but just as they begin feeling like a family again, disaster strikes.

But this catastrophe is just a tiny taste of the true danger lurking ahead — somewhere out there, someone wants to make sure the Dunne family never leaves paradise alive.
