Far out to sea and deep below the whispering waves lives a merman called Nen. Nen spends his days exploring his underwater kingdom, but something is missing: his heart is empty. So, Nen ventures to the forbidden world above and it is here that he meets Ernest, a lonely fisherman.

But can two people from different worlds be together and what will happen when a terrifying storm gathers? A lyrical, beautiful celebration of love, acceptance and faith, with a gentle message about how we treat our oceans, and each other.
