While already Die Schwarzwaldklinik was inspired by General Hospital, Rademann that time tried to transform the successful US-series Fantasy Island into a German version.
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.
Although copying its concept of happy-ending drama stories garnished with pictures of beautiful landscapes, Insel der Träume could not repeat the success of Die Schwarzwaldklinik and was cancelled after the second season.
