One But... Leon (1988)

After the sudden death of his grandfather, the pervasive Stathis suddenly finds himself president of a large public limited company but is in danger of being out of business because he does not find the shares he has inherited. These young people are also looking for these shares, who manage to turn all the members of the board against them. But Stathis shows, from the very beginning, that he is the absolute sovereign and does not raise any doubts, while at the same time instructs a private detective to find the valuable shares.
