After dancing together in the nightclub, seven young people (five men and two women) were told they had won the dance competition that night and were instructed to board a small plane to take them on vacation. On the contrary, they were ultimately trapped on a small island along with a co pilot of the plane. In search of shelter, the eight went to a mansion where they met a cunning looking butler who announced that he knew all of them and had been looking forward to their arrival. After a few musical numbers, the victims began to die one after another. Who could be the culprit? Will any of them escape his pursuit?
