Gavin Weald lives with his six-year old daughter Océan and their dog Suzy in a newly rebuilt pink house. It is only a few months since a devastating flood swept through their home, with heartbreaking consequences.

Gavin is trying desperately to carry on, but wakes each night to his daughter's cries and his own fears for the future. So one day he does the only thing he can think of: he takes his daughter and his dog down to the marina, to his old boat Romany which hasn't set sail in years, and embarks upon a voyage to make his peace with the waters. They set sail into deep open ocean, watch fish and dolphins leap from the waves, and head for the Caribbean archipelago that Gavin longed to explore as a younger man, before he fell in love with a woman and moored his boat for what he thought was the last time.
