 Each episode was about a guest coming from Germany to that isle hosted by the older, always white-dressed "professor" Gregor Sartorius and his young daughter Sandra.Different from its American model (but according to "Die Schwarzwaldklinik" as a medical drama), it was openly presented that the island's visitors came there to become healed from a psychological problem.After a number of (therapeutical) talks with Sartorius or his daughter, the guests were brought to a mysterious waterfall, where they recognised during some kind of a vision the (true) reason for their problems.
