It was supposed to be just an ordinary holiday on sunny Kos, but Toni has to rescue a beautiful local girl, a talented free-diver, from the clutches of kidnappers. When it appears that nobody else can be trusted, Toni must reluctantly rely on his step-brothers' assistance.
Unfortunately the movie The Island of Secrets is not yet available on HBO Max.
