Industrialist George Stark (Teodoro Corra) invites a small group of wealthy friends to his private island for a weekend of relaxation and light business. He wants them to meet the brilliant chemist Gerry Farrell (William Berger) who has invented a new chemical process. Against his wishes, Farrell is engaged in business discussions revolving around millions of dollars worth of investment. As each of the potential investors goes behind each other's back, fear and mistrust grow, particularly once the guests begin turning up dead. English Dubbed Version.
