The dolphin child

When Marijn visits a dolphinarium with his school one day, something very strange happens. Before he knows it, he dives into the water and swims with the dolphins as if he has never done anything else in his life. His mother realizes that it is high time to give Marijn an explanation for this behavior. She tells him a few things from the past, even though it is painful for her. A while later, the two of them leave for the Bahamas, where Marijn was born, but where his father also mysteriously disappeared. They want to find out the truth once and for all.
